Isihlungi Se-Microwave Esenziwe Ngokwezifiso esingu-471-481MHz Cavity nge-Keenlion
Isihlungi se-Cavityihlinzeka ngomkhawulokudonsa wefrikhwensi ongu-10mhz ukuze kuhlungwe okunembile.471-481MHz Isihlungi seCavity sinqanyulwa ngaphezu kwemvamisa ethile.Isihlungi se-Keenlion sika-471-481MHz Cavity iyunithi yokungenzi lutho eyakhiwe ngokunemba eyakhelwe amaketango ahlanzekile okwamukela i-UHF. Ifakwe embonini yethu yeminyaka engu-20, sonke isihlungi se-Cavity esingu-471-481MHz sifakwe ngesiliva, sishunwe ngesandla futhi siqinisekiswa ku-Keysight PNA-X ukuze ilethe Ukulahleka Kokufaka ≤1.0 dB kuyilapho inikeza Ukwenqaba ≥40 dB @ 276 MHz kanye Nokwenqatshwa ≥6 MHz ≥7 ≥60 MHz ≥60 MHz ≥60 MHz ukulawula ukuphazamiseka.

Izinhlelo zokusebenza
Faka Isihlungi Se-Cavity esingu-471-481MHz phakathi komsakazo nothingo ku-PMR, LoRa, SCADA neziphindaphinda ezingasindi. Ukuhlolwa kwenkundla kubonisa ukwenqatshwa kwesayithi okuhlanganyelwe okuthuthukisiwe ngo-45 dB ngemva kokufaka Isihlungi se-Cavity esingu-471-481MHz, sisusa ukungezwani komzimba ezinsizeni eziseduze ze-VHF kanye ne-700 MHz.
