These brand new Cavity Bandpass/Bandreject Duplexers are perfect for UHF PRS Repeaters, with their 0.75 MHz Transmit / Receive split and are factory aligned to the specific channel required. These cavity filters are the answer to reduce receiver interference, desensitization or blocking, basically preventing interaction between transmitters in combining systems, reducing off channel signals, harmonic or spurious outputs from transmitters running nearby. Cavity filters are finely tuned to vastly improve PRS repeater receiver performance. These Cavity Filters also combine the transmit and receive signals into one antenna, instead of 2 separate antennas being required, one for transmit and one for receive.
The attached spectrum analyzer capture displays the characteristics for a UHF PRS Channel 8 repeater.
