He aha ke kumu o kahi resonator cavity? 2878-2882MHz Cavity Filter i nā Pūnaewele Passive Hou

Mālama kahi resonator cavity i ka ikehu RF ma ke ʻano nalu kū a hoʻihoʻi wale ia i ka alapine i manaʻo ʻia.Kānana Lua 2878-2882MHzHoʻopili ka mea i hana ʻia e Keenlion ma Chengdu i kēia kumumanaʻo ma o kahi lua coaxial hapaha-nalu: wehewehe nā paia i uhi ʻia i ke kālā i kahi ʻano eigen 2880 MHz, ʻoiai ua hoʻihoʻi ʻia ka ikehu off-band i ke kumu. No ka mea, ʻaʻohe ʻāpana hana o ka 2878-2882MHz Cavity Filter, ua kaupalena ʻia ka pohō hoʻokomo i nā pohō alakaʻi a me nā dielectric—noho nā waiwai i ana ʻia ma lalo o 1.0 dB ma ka puka makani 4 MHz.

Hoʻolālā ʻenehana a me ka hana

Hoʻohana ka 2878-2882MHz Cavity Filter i nā lua Q kiʻekiʻe e hoʻokō i ka pohō hoʻokomo liʻiliʻi (≤1.0 dB) a me ke koho kūikawā (>40 dB rejection ma ±5 MHz offset). ʻO kona hale liʻiliʻi, e ana ana he 74 × 31 × 30 mm, hoʻohui pono i nā ʻōnaehana i kaupalena ʻia e ka lewa e like me nā pods UAV a i ʻole nā lekiō IoT liʻiliʻi. Hana pono ke kānana ma waena o nā mahana mai -55°C a i 85°C, me VSWR i mālama ʻia ma lalo o 1.5:1 e hōʻemi i nā ʻōuli hōʻailona. Hoʻomaʻamaʻa kēlā me kēia ʻāpana i ka hoʻāʻo VNA automated 100% e hōʻoia i nā kikoʻī e like me ka lawelawe ʻana i ka mana (20W CW) a me ka band-edge steepness.

Envelopa Mekanika

ʻO ka nui holoʻokoʻa he 74 × 30 × 31mm—ʻoi aku ka liʻiliʻi ma mua o ka hapa nui o nā hāmeʻa SAW—akā naʻe, lawelawe ka 2878-2882MHz Cavity Filter i 20 W CW. ʻElua mau lua M2 ma nā kikowaena 15 mm e ʻae i ka 2878-2882MHz Cavity Filter e hoʻopaʻa pololei ʻia i kahi paia alumini, e wehe ana i ka pono no kahi bracket kaʻawale a mālama i nā grama makamae i nā UAV a i ʻole nā kūkulu lima.

Iwi kuamoʻo o ka hale hana

ʻO nā mīkini hana 20 makahiki o Keenlion, nā papa, nā mele a me nā wili i kēlā me kēia kānana Cavity 2878-2882MHz ma lalo o hoʻokahi hale. ʻEhiku lā ka manawa alakaʻi no nā ʻāpana maʻamau, kanahākumamāwalu hola no nā kauoha hou. Ua hōʻoia ʻia ka pohō hoʻokomo ≤1.0 dB a me ka hōʻole ʻana ≥40 dB ma kēlā me kēia kānana Cavity 2878-2882MHz; hoʻouna ʻia nā laʻana manuahi i loko o kanahākumamāwalu hola a ʻae ʻia nā māhele alapine maʻamau me ka ʻole MOQ.

Kūpono o ka mākeke

"He aha ke kumu o kahi resonator cavity?" hiki i nā ʻenekinia ke kuhikuhi i ka 2878-2882MHz Cavity Filter: hoʻonohonoho ia i kahi puka paʻa 4 MHz ma 2.48 GHz, mālama i ka spuious mai nā polokalamu ISM a hana pēlā me ka metala, ʻaʻole ka polokalamu. tom@keenlion.comno nā pepa ʻikepili, nā prototypes a me ke kumukūʻai hale hana ma ka 2878-2882MHz Cavity Filter—e hoʻouna aku i ka lā ʻapōpō, e laka i kāu spectrum i kēia lā.
