Iyini injongo ye-cavity resonator? Isihlungi se-Cavity esingu-2878-2882MHz kumaNethiwekhi Angasebenzi Anamuhla

I-cavity resonator igcina amandla e-RF ngendlela yamagagasi amile futhi iwabuyisela kuphela ngemvamisa ehlosiwe.Isihlungi Semihume esingu-2878-2882MHzOkukhiqizwe yiKeenlion eseChengdu kusebenzisa lesi simiso nge-quarter-wave coaxial cavity: izindonga ezimbozwe ngesiliva zichaza imodi ye-eigen engu-2880 MHz, kuyilapho amandla e-off-band ebonakala emuva emthonjeni. Ngenxa yokuthi i-2878-2882MHz Cavity Filter ayinazo izingxenye ezisebenzayo, ukulahlekelwa kokufakwa kunqunyelwe ekulahlekelweni kwe-conductor kanye ne-dielectric—amanani alinganisiwe ahlala ngaphansi kuka-1.0 dB kulo lonke iwindi le-4 MHz.

Umklamo Wobuchwepheshe Nokusebenza

I-2878-2882MHz Cavity Filter isebenzisa imigodi ephezulu ye-Q ukuze kufezwe ukulahlekelwa okuncane kokufakwa (≤1.0 dB) kanye nokukhetha okungavamile (ukwenqatshwa kwe->40 dB ku-±5 MHz offset). Indlu yayo encane, elinganisa i-74 × 31 × 30 mm, ihlangana kahle nezinhlelo ezivinjelwe isikhala njenge-UAV pods noma imisakazo ye-IoT encane. I-filter isebenza ngokuthembeka kuwo wonke amazinga okushisa asukela ku--55°C kuya ku-85°C, kanti i-VSWR igcinwe ngaphansi kwe-1.5:1 ukuze kuncishiswe ukubonakaliswa kwesignali. Iyunithi ngayinye ihlolwa i-VNA ezenzakalelayo engu-100% ukuqinisekisa imininingwane efana nokuphathwa kwamandla (20W CW) kanye nokuqina kwebhendi.

Imvilophu Yomshini

Usayizi ophelele ungama-74 × 30 × 31mm—uncane kunamadivayisi amaningi e-SAW—kodwa i-2878-2882MHz Cavity Filter iphatha i-20 W CW. Izimbobo ezimbili ze-M2 ezikhungweni ze-15 mm zivumela i-2878-2882MHz Cavity Filter ukuthi inamathele ngqo odongeni lwe-aluminium, okususa isidingo se-bracket ehlukile futhi konga amagremu ayigugu ku-UAV noma ezakhiweni ezibanjwa ngesandla.

Umgogodla Wefektri

Imishini yesitshalo seminyaka engu-20 sikaKeenlion, amapuleti, ama-tune kanye nama-weld njalo nge-2878-2882MHz Cavity Filter ngaphansi kophahla olulodwa. Isikhathi sokuhola siyizinsuku eziyisikhombisa zezingxenye ezijwayelekile, amahora angamashumi amane nesishiyagalombili ama-oda aphindaphindwayo. Ukulahlekelwa kokufakwa ≤1.0 dB kanye nokwenqatshwa ≥40 dB kuqinisekisiwe kuyo yonke i-2878-2882MHz Cavity Filter; amasampula amahhala athunyelwa zingakapheli amahora angamashumi amane nesishiyagalombili futhi ukuhlukaniswa kwemvamisa ngokwezifiso kuyamukelwa ngaphandle kwe-MOQ.

Ukufaneleka Kwemakethe

“Iyini injongo ye-cavity resonator?” onjiniyela sebengakhomba i-2878-2882MHz Cavity Filter: ibeka isango eliqinile le-4 MHz ku-2.48 GHz, igcina amadivayisi e-ISM angathembekile futhi ikwenza lokho ngensimbi, hhayi ngesofthiwe. tom@keenlion.comukuze uthole amashidi edatha, ama-prototype kanye namanani efektri ku-2878-2882MHz Cavity Filter—thumela kusasa, vala i-spectrum yakho namuhla.
