I-VHF Tunable Filter Esebenza Kusuka Ku-152-174MHz Ngezixhumi ze-N
Isihlungi se-VHF i-JX-SF1-152174-215N siwuhlobo olulodwa lwesihlungi esingaguquleka se-VHF esisebenza ukusuka ku-152-174MHz esinomkhawulokudonsa ongu-5-15MHz. ukulahlekelwa ngaphansi kuka-0.5-2.2dB kuma-bandwidths ahlukene, ukulahlekelwa kokubuyisela okungaphezu kuka-20dB, nokwenqatshwa okuphezulu futhi.
Uhlobo olunjalo lwesihlungi se-cavity senzelwe ukulungisa imvamisa yaso ngokuya ngefrikhwensi eguqulekayo, ngakho-ke singasetshenziswa kabanzi kwizixazululo ze-VHF. Njengomklami wesihlungi se-RF, izihlungi eziguqulekayo zingenziwa ngokwezifiso futhi. Njengoba kuthenjisiwe, zonke izingxenye ze-RF ezingenzi lutho ezivela ku-Jingxin zinewaranti yeminyaka emi-3.

| Mayelana nepharamitha ngombala oluhlaza okwesibhakabhaka, yenziwa ngokuya ngomklamo, kodwa engakwazi ukuhlolwa ngaphambi kokulethwa. | |
Izingxenye ze-RF Passive zangokwezifiso
Njengomkhiqizi wezinto ezisetshenziswayo ze-RF, i-Jingxin ingakwazi ukuklama ezihlukahlukene ngokuvumelana nezicelo zamakhasimende.
Izinyathelo Ezi-3 Kuphela Zokuxazulula Inkinga Yakho Yengxenye Ye-RF Passive
1. Ukuchaza ipharamitha nguwe.
2. Ukunikeza isiphakamiso sokuqinisekiswa nguJingxin.
3. Ukukhiqiza i-prototype yokuhlolwa kwe-Jingxin.
