ʻO Sichuan Keenlion Microwave Technology——Nā kānana

ʻO Sichuan Keenlion Microwave Technology I hoʻokumu ʻia ma 2004, ʻo Sichuan Keenlion Mircrowave techenology CO., Ltd. ka mea hana nui o nā ʻāpana Passive Mircrowave ma Sichuan Chengdu, Kina.

Hāʻawi mākou i nā ʻāpana mirrowave kiʻekiʻe a me nā lawelawe pili no nā noi microwave ma ka home a ma waho. ʻO nā huahana ke kumu kūʻai, me nā mea hoʻokaʻawale mana like ʻole, nā mea hoʻopili kuhikuhi, nā kānana, nā hui pū, nā duplexers, nā ʻāpana passive i hana ʻia, nā mea hoʻokaʻawale a me nā circulators. Hoʻolālā kūikawā ʻia kā mākou huahana no nā kaiapuni koʻikoʻi a me nā mahana. Hiki ke hoʻonohonoho ʻia nā kikoʻī e like me nā koi o ka mea kūʻai aku a pili i nā mea āpau maʻamau a kaulana hoʻi me nā bandwidth like ʻole mai DC a 50GHz.

Nā kānana

Hiki i ka kānana ke kānana pono i ke alapine o kahi alapine kikoʻī i loko o ke kaula mana a i ʻole ke alapine ʻē aʻe ma mua o ke kiko alapine, loaʻa kahi hōʻailona kumu mana o kahi alapine, a i ʻole e hoʻopau i kahi hōʻailona mana alapine.

 

Hoʻolauna

ʻO ka kānana he mea koho e hiki ai i ka ʻāpana alapine kikoʻī i ka hōʻailona ke hala, a ua hoʻemi nui ʻia nā ʻāpana alapine ʻē aʻe. Hiki ke kānana ʻia kēia hopena koho me ka hoʻohana ʻana i ka kānana mai ka walaʻau hoʻopilikia a i ʻole e hana i ka loiloi spectrum. I nā huaʻōlelo ʻē aʻe, ua kapa ʻia ʻo ia he kānana e hiki ai ke hoʻoheheʻe i kahi ʻāpana alapine i ka hōʻailona, ​​​​a hoʻemi nui a hoʻopaʻa paha i nā ʻāpana alapine ʻē aʻe. ʻO ka kānana kahi mea i kānana ʻia e ka nalu. ʻO ka "Wave" kahi manaʻo kino ākea loa, ma ke kahua o ka ʻenehana uila, ua kaupalena ʻia ka "wave" i ke kaʻina o ka unuhi ʻana i ka waiwai o nā nui kino like ʻole i ka manawa. Hoʻololi ʻia ke kaʻina hana i kahi hana manawa o kahi volta a i ʻole kēia ma o nā ʻano nui kino, a i ʻole nā ​​hōʻailona. No ka mea he waiwai mau ka manawa hoʻololi ponoʻī, ua kapa ʻia ʻo ia he hōʻailona manawa mau, a ua kapa ʻia ʻo ia he hōʻailona analog.

ʻO ka kānana he manaʻo koʻikoʻi i ka hana hōʻailona, ​​a ʻo ka hana o ka kānana kaapuni i ka DC voltage regulator e hoʻemi i ka ʻāpana AC i ka puʻupuʻu DC e like me ka hiki, e mālama i kāna mea hoʻohui DC, i hoʻohaʻahaʻa ʻia ka coefficient ripple volta pukana, lilo ka nalu i Smooth.

Tʻo ia nā palena nui:

Alapine waena: ʻO ka alapine f0 o ke kānana passband, e lawe maʻamau i ka f0 = (f1 + f2) / 2, f1, f2 ma ke ʻano he band pass a i ʻole kānana pale pale ʻana i ka hema, kū'ē i ka 1 dB a i ʻole 3DB ke kiko alapine. Hoʻopili pinepine ka kānana narrowband i ka bandwidth passband me ka wahi liʻiliʻi o ka poho hoʻokomo.

lā palena pau: Hōʻike i ke ala i ke ala o ka passband o ka kānana pass haʻahaʻa a me ka band pass o ka kānana pass kiʻekiʻe. Hōʻike maʻamau ia ma kahi wahi poho pili o 1 dB a i ʻole 3DB. ʻO ka poho pili pili i ka kuhikuhi haʻahaʻa: ʻo ka haʻahaʻa haʻahaʻa e pili ana i ka hoʻokomo DC, a ʻo ka Qualcomm i hoʻokumu ʻia ma ka lawa o ka alapine kiʻekiʻe o ka pā parasitic.

ʻO ka bandwidth passband: pili i ka laulā spectrum e pono ai e hele, BW = (F2-F1). Hoʻokumu ʻia ka F1, F2 i ka poho hoʻokomo ma ke alapine waena F0.

Nalo hoʻokomo: Ma muli o ka hoʻokomo ʻana o ka kānana i ka lewa o ka hōʻailona kumu i ke kaapuni, nā poho i ke kikowaena a i ʻole ke alapine ʻoki ʻoki, e like me ke koi ʻana i ka pau ʻana o ka pūʻulu holoʻokoʻa e hoʻohālikelike.

Ripple: E pili ana i ka 1DB a i ʻole 3DB bandwidth (cutoff frequency), ʻo ka poho hoʻokomo e hoʻololi i ka piko o ke alapine ma ka pihi mean.

Nā loli kūloko: Hoʻokomo poho i loko o ke ala ala me nā ʻokoʻa alapine. ʻO ka loli o ka band i ka bandwidth 1db he 1db.

Kū i ka pūʻulu: E ana inā maikaʻi ka hōʻailona ma ka passband i ka kānana e hoʻohālikelike i ka hoʻouna ʻana o ka lawe. Hoʻohālikelike kūpono VSWR = 1: 1, ʻoi aku ka nui o VSWR ma mua o 1 i ka wā like ʻole. No kahi kānana maoli, ʻoi aku ka liʻiliʻi o ka bandwidth e hōʻoluʻolu ana i ka VSWR ma mua o 1.5: ʻoi aku ka liʻiliʻi o 1 ma mua o BW3DB, ʻo ia ka helu o ka BW3DB a me ke kauoha kānana a hoʻokomo i ka poho.

Pohō o ka lāʻau: ʻO ka helu o nā decibels (DB) lākiō o ka mana hoʻokomo hōʻailona awa a me ka mana i ʻike ʻia ua like ia me 20 Log 10ρ, ρ he koena hoʻohālikelike uila. ʻAʻole pau ka poho o ka hoʻihoʻi ʻana i ka wā e komo ai ka mana hoʻokomo e ke awa.

Ka hana hou ʻana o ka hoʻopau ʻana i ka ʻili: he hōʻailona koʻikoʻi o ka maikaʻi o ka hana koho kānana. ʻO ke kiʻekiʻe o ka mea hōʻailona, ​​ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka hōʻailona interference waho. ʻElua ʻano manaʻo maʻamau: ʻo ke ʻano no ka hoʻopaʻa ʻana i ka nui o ke kaohi ʻana o DB o kahi band crossing frequency fs, ʻo ke ʻano helu ʻana ʻo ka emi ʻana o FS; 'ē aʻe hōʻike no ka manaʻo o ka hōʻailona kānana threading a me ka pono rectangle hoʻokokoke mai - Rectangular coefficient (KXDB oi ma mua o 1), KXDB = BWXDB / BW3DB, (X hiki ke 40dB, 30dB, 20DB, etc.). ʻOi aku ka nui o nā rectangular rectangular, ʻoi aku ka kiʻekiʻe o ka rectangularity - ʻo ia hoʻi, ʻoi aku ka kokoke i ka waiwai kūpono 1, a ʻoi aku ka paʻakikī o ka hana ʻana.

Hoʻopaneʻe: ʻO ka hōʻailona e pili ana i ka manawa i koi ʻia no ka hōʻailona e hoʻouna i ka hana diagonal frequency, ʻo ia hoʻi, TD = DF / DV.

Ka laina laina i loko o ka pūnaʻi: ʻO kēia kānana hōʻailona hōʻailona ʻo ia ka distortion pae o ka hōʻailona i hoʻouna ʻia i ka passband. ʻO ka kānana i hoʻolālā ʻia e ka hana pane o ka pae laina he laina laina maikaʻi.

Hoʻokaʻawale nui

Hoʻokaʻawale ʻia i kahi kānana analog a me kahi kānana kikohoʻe e like me ka hōʻailona e hana ʻia nei.

Hoʻokaʻawale ʻia ke ala o ka hele ʻana o ka kānana passive i ka low pass, high pass, bandpass, a me nā kānana āpau.

kānana ala haʻahaʻa:hiki iā ia ke hāʻawi i nā mea haʻahaʻa haʻahaʻa a i ʻole DC i ka hōʻailona, ​​e kāohi i nā ʻāpana alapine kiʻekiʻe a i ʻole ke keakea a me ka walaʻau;

kānana kiʻekiʻe: hiki iā ia ke hāʻawi ʻia nā ʻāpana alapine kiʻekiʻe i ka hōʻailona, ​​e kāohi i ka haʻahaʻa haʻahaʻa a i ʻole nā ​​mea DC;

Kānana Band Pass: Hāʻawi ia i nā hōʻailona e hāʻawi ʻia, hoʻopaʻa ʻia nā hōʻailona, ​​keakea, a me ka walaʻau ma lalo a ma luna paha o ka band;

Kānana kāʻei: Kāohi ia i nā hōʻailona i loko o kekahi pūʻulu alapine (frequency band) e ʻae i nā hōʻailona ʻē aʻe ma waho o ka pūʻali, ʻike ʻia hoʻi he kānana notch.

kānana holo a pau: ʻO ke kānana holo piha, ʻo ia hoʻi, ʻaʻole e loli ka amplitude o ka hōʻailona i loko o ka laulā piha, ʻo ia hoʻi, ʻo ka loaʻa ʻana o ka amplitude o ka laulā piha e like me 1. Hoʻohana ʻia nā kānana holoʻokoʻa holoʻokoʻa i ka phase phase, ʻo ia hoʻi, hoʻololi ka pae o ka hōʻailona hoʻokomo, a ʻo ka mea maikaʻi ʻo ka hoʻololi ʻana o ka pae e like me ke alapine, e like me ka ʻōnaehana hoʻopaneʻe manawa.

ʻO nā ʻāpana ʻelua i hoʻohana ʻia he kānana passive a me ka hana.

Ma muli o ke kau ʻana o ka kānana, ua māhele ʻia i loko o kahi kānana pā a me kahi kānana panel.

Ma ka papa, e hoʻokomo i ka papa, e like me ka PLB, kahi kānana moʻo JLB. ʻO nā mea maikaʻi o kēia kānana he mea waiwai, a ʻo ka hemahema, ʻaʻole maikaʻi ka kānana alapine kiʻekiʻe. ʻO kāna kumu nui:

1. ʻAʻohe mea kaʻawale ma waena o ka hoʻokomo a me ka hoʻopuka o ka kānana, kahi e pili ana i ka hoʻohui;

2, ʻaʻole haʻahaʻa loa ka impedance grounding o ka kānana, hoʻonāwaliwali i ka hopena bypass kiʻekiʻe;

3, ʻo kahi ʻāpana o ka pilina ma waena o ka kānana a me ka chassis e hoʻopuka i ʻelua mau hopena ʻino: ʻo kekahi ka hoʻopili electromagnetic o ka lumi o loko o ka chassis, kahi i hoʻokomo pono ʻia i kēia laina, ma ke kaula, a hoʻomālamalama i ka kānana ma o ka radiation cable. hāʻule; ʻo ka mea ʻē aʻe, ua kānana ʻia ka hoʻopili ʻana o waho e ka kānana kānana ma ka papa, a i ʻole e hoʻopuka pololei ʻia ka radiation a i ʻole pololei i ke kaapuni ma ka papa kaapuni, e hopena i nā pilikia sensitivity;

Hoʻokomo pinepine ʻia nā papa hoʻonohonoho kānana, nā mea hoʻopili kānana a me nā kānana panel ʻē aʻe ma ka papa metala o ka chassis pale. No ka mea ua hoʻokomo pololei ʻia ma ka papa metala, ua kaʻawale loa ka hoʻokomo a me ka hoʻopuka ʻana o ka kānana, ua paʻa maikaʻi ka honua, a ua kānana ʻia ka hoʻopili ʻana i ke kaula ma luna o ke awa chassis, no laila ua kūpono loa ka hopena kānana.

kānana hāliu

ʻO ka kānana passive kahi kaapuni kānana e hoʻohana ana i kahi resistor, reactor, a me kahi mea capacitor. I ka manawa o ke alapine resonant, he liʻiliʻi ka waiwai impedance kaapuni, a nui ka impedance kaapuni, ua hoʻololi ʻia ka waiwai o ka ʻāpana kaapuni i kahi hiʻohiʻona harmonic frequency, a hiki ke kānana ʻia ka manawa harmonic; i ka wā i haku ʻia ai kekahi mau alapine harmonic, a laila hiki ke kānana ʻia ka hiʻohiʻona pili i ka alapine harmonic, a ʻo ke kānana ʻana i ka helu nui harmonic (3, 5, 7) e loaʻa i ka haʻahaʻa impedance bypass. ʻO ke kumu nui no nā helu like ʻole o nā harmonics, ʻo ka hoʻolālā ʻana i ke alapine harmonic he liʻiliʻi, e hoʻokō i ka hopena splitting o ka manawa harmonic, e hāʻawi ana i kahi alahele no nā harmonics kiʻekiʻe prefiltered e hoʻokō i ka nalu hoʻomaʻemaʻe.

Hiki ke hoʻokaʻawale ʻia nā kānana passive i nā kānana capacitive, nā ʻāpana kānana mea kanu mana, nā kānana kānana L-RC, nā ʻāpana kānana π ʻano RC, nā ʻāpana kānana RC multi-section, a me nā kaapuni kānana LC. E kaomi e hana i loko o kahi kānana hoʻoheheʻe hoʻokahi, kānana hoʻoheheʻe pālua, a me ke kānana ala kiʻekiʻe. Loaʻa i ka kānana passive nā mea maikaʻi aʻe: he maʻalahi ke ʻano, he haʻahaʻa ke kumukūʻai hoʻopukapuka, a hiki i ka mea reactive i loko o ka ʻōnaehana ke uku i ka mea mana o ka ʻōnaehana. Hoʻomaikaʻi ia i ka mea mana o ka pā; kiʻekiʻe ka paʻa o ka hana, maʻalahi ka mālama ʻana, ka maturation ʻenehana, a me nā mea ʻē aʻe. Nui nā hiʻohiʻona o nā hemahema o nā kānana passive: ʻo ka hopena o nā ʻāpana mana mana, ka waiwai impedance ʻōnaehana a me ka helu nui o nā alapine resonant e loli pinepine e like me nā kūlana hana; ʻo ka kānana harmonic he haiki, ʻo ka helu nui wale nō o nā manawa nui e hiki ke kānana wale ʻia i Harmonics, a i ʻole ma muli o nā koena parallel, hoʻonui i nā harmonics; ka hoʻohui ʻana ma waena o ka kānana a me ka uku hoʻihoʻi a me ka hoʻoponopono kaomi; e like me ke kahe ʻana o kēia manawa ma ka kānana, hiki ke hoʻonui i ka hana o nā mea hana; ʻOi aku ka nui o nā mea hoʻopau, nui ke kaumaha a me ka nui; ʻilihune ka paʻa o ka hana. No laila, ʻo kahi kānana hana me ka hana ʻoi aku ka nui o nā noi.

Hiki iā mākou ke hana i nā ʻāpana passive rf e like me kāu mau koi. Hiki iā ʻoe ke komo i ka ʻaoʻao hoʻoponopono e hāʻawi i nā kikoʻī āu e pono ai.
