He aha ke kumu o ka resonator lua? 2878-2882MHz Cavity kānana i nā pūnaewele passive hou

Mālama ka cavity resonator i ka ikehu RF ma ke ʻano hawewe kū a hoʻihoʻi wale ia i ka alapine i manaʻo ʻia. ʻO ka2878-2882MHz Kānana Anahana ʻia e Chengdu-based Keenlion e pili ana i kēia kumumanaʻo ma o ka hawewe coaxial cavity: ʻo nā paia i uhi ʻia i ke kālā e wehewehe i kahi 2880 MHz eigen-mode, ʻoiai e ʻike ʻia ka ikehu o waho i ke kumu. No ka mea, ʻaʻohe mea hana o ka 2878-2882MHz Cavity Filter, ua kaupalena ʻia ka poho hoʻokomo i nā poho conductor a me dielectric—e mau ana nā waiwai i ana ma lalo o 1.0 dB ma ka pukaaniani 4 MHz.

Hoʻolālā ʻenehana a me ka hana

Hoʻohana ka 2878-2882MHz Cavity Filter i nā lua Q kiʻekiʻe e loaʻa ai ka liʻiliʻi o ka hoʻokomo ʻana (≤1.0 dB) a me ke koho ʻokoʻa (>40 dB hōʻole ma ± 5 MHz offset). ʻO kona hale paʻa, me ke ana ʻana he 74 × 31 × 30 mm, hoʻohui pono ʻia i loko o nā ʻōnaehana hoʻopaʻa ʻia e like me UAV pods a i ʻole nā lekiō IoT compact. Hana pono ka kānana ma waena o nā mahana o -55°C a i 85°C, me ka mālama ʻia ʻana o VSWR ma lalo o 1.5:1 e hōʻemi i nā noʻonoʻo hōʻailona. Hoʻokomo ʻia kēlā me kēia ʻāpana i ka hoʻāʻo VNA automated 100% e hōʻoia i nā kikoʻī e like me ka hoʻohana ʻana i ka mana (20W CW) a me ka ʻoi loa o ka band-edge steepness.

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

Ka iwi kuamoʻo hale hana

ʻO nā mīkini mea kanu 20 makahiki a Keenlion, nā papa, nā kani a me nā weld i kēlā me kēia 2878-2882MHz Cavity Filter ma lalo o hoʻokahi hale. ʻEhiku lā ka manawa alakaʻi no nā ʻāpana maʻamau, kanahākūmāwalu hola no nā kauoha hou. Hoʻokomo ʻia ka poho ≤1.0 dB a me ka hōʻole ≥40 dB i kēlā me kēia 2878-2882MHz Cavity Filter; ʻAʻole ʻae ʻia nā mea hoʻohālike manuahi i loko o nā hola he kanahākūmāwalu a ʻae ʻia nā ʻāpana alapine maʻamau ma ka MOQ ʻole.
