Akamaro k'icyuma gihindura imiyoboro y'amashanyarazi (cavity resonator) ni akahe? Akayunguruzo k'imiyoboro y'amashanyarazi ya 2878-2882MHz mu miyoboro ya none idafite imiyoboro y'amashanyarazi.

Resonator yo mu gisenge ibika ingufu za RF mu buryo buhagaze kandi ikayisubiza gusa ku gipimo cyagenwe.Akayunguruzo k'ubuso ka 2878-2882MHzIkorwa na Keenlion yo muri Chengdu ikoresha iri hame binyuze mu mwobo wa coaxial wa kane: inkuta zikozwe mu ifeza zigaragaza uburyo bwa eigen bwa 2880 MHz, mu gihe ingufu zidasanzwe zigaruka ku isoko. Kubera ko Filter ya Cavity ya 2878-2882MHz nta bice bikora, igihombo cyo kwinjira kigarukira ku gihombo cya conductor na dielectric - agaciro kapimwe kaguma munsi ya 1.0 dB mu idirishya rya 4 MHz.

Igishushanyo mbonera cya tekiniki n'imikorere

Iyi Filter ya Cavity ya 2878-2882MHz ikoresha utwobo twinshi twa Q kugira ngo igabanuke cyane mu gushyiramo (≤1.0 dB) no guhitamo neza (kwanga >40 dB kuri ±5 MHz offset). Inzu yayo nto, ifite uburebure bwa mm 74 × 31 × 30, ihuzwa neza na sisitemu zidafite aho zihuriye n'umwanya nka UAV pods cyangwa radiyo nto ya IoT. Iyi filter ikora neza mu bushyuhe buri hagati ya -55°C na 85°C, VSWR iguma munsi ya 1.5:1 kugira ngo igabanye urumuri rw'ibimenyetso. Buri gice gikorerwa isuzuma rya VNA ryikora 100% kugira ngo cyemeze ibipimo nk'uburyo bwo gucunga ingufu (20W CW) no guhagarara kw'umurongo.

Ibahasha ya Mekanike

Ingano rusange ni 74 × 30 × 31mm—ni ntoya ugereranyije n’ibikoresho byinshi bya SAW—nyamara Filter ya 2878-2882MHz ifata 20 W CW. Utwobo tubiri twa M2 ku gice cya 15 mm twemerera Filter ya 2878-2882MHz gufatishwa ku rukuta rwa aluminiyumu, bikuraho gukenera agace gatandukanye kandi bigatuma garama z’agaciro zigabanuka mu bikoresho bya UAV cyangwa ibikoresho bifatwa n’intoki.

Uruti rw'umugongo rw'uruganda

Imashini, amasahani, imiyoboro n'imashini zo mu bwoko bwa Keenlion zimara imyaka 20 zikora uruganda, zikora plaque, zitunganya kandi zisudira buri firigo ya 2878-2882MHz munsi y'igisenge kimwe. Igihe cyo kuyobora ni iminsi irindwi ku bice bisanzwe, amasaha mirongo ine n'umunani ku bicuruzwa bisubirwamo. Igihombo cyo gushyiramo ≤1.0 dB no kwangwa ≥40 dB byemejwe kuri buri firigo ya 2878-2882MHz; ingero zoherezwa ku buntu mu masaha mirongo ine n'umunani kandi kugabanya inshuro zihariye byemerwa nta MOQ.

Isoko rikwiranye

“Intego ya cavity resonator ni iyihe?” ubu noneho bashobora kwerekana Cavity Filter ya 2878-2882MHz: ishyiraho gate ikomeye ya 4 MHz kuri 2.48 GHz, ikarinda ibikoresho bya ISM bitari ukuri kandi ikabikora ikoresheje icyuma, ntabwo ari porogaramu. tom@keenlion.comku mpapuro z'amakuru, ibishushanyo mbonera n'ibiciro by'uruganda kuri 2878-2882MHz Cavity Filter—ohereza ejo, funga spectrum yawe uyu munsi.
