Fyuluta Yophimba M'mimbaimapereka bandwidth yopapatiza ya 10mhz kuti isefedwe molondola. 471-481MHz Cavity Filter imadula pamwamba pa ma frequency enaake. 471-481MHz Cavity Filter ya Keenlion ndi chipangizo chopangidwa mwaluso kwambiri chomwe chimapangidwa kuti chigwiritsidwe ntchito ndi ma UHF transmit-receiver cha unyolo woyera. Chopangidwa mu fakitale yathu ya zaka 20, 471-481MHz Cavity Filter iliyonse imapangidwa ndi siliva, imakonzedwa ndi manja ndipo imatsimikiziridwa pa Keysight PNA-X kuti ipereke Insertion Loss ≤1.0 dB pamene ikupereka Rejection ≥40 dB @ 276 MHz ndi Rejection ≥40 dB @ 676 MHz—chofunika kwambiri pakuwongolera kusokoneza kwa band yapafupi.
