8-Resonator Duplexer for the 80 MHz Band rest 6 cavity filters 90.00 SOLD
The DPF 4/8 S-4/13 is an 8-resonator duplex filter for duplex radiotelephones.
This filter is primarily intended for equipment, where the TX and the RX operate on single but split frequencies, but it can also, however with slightly reduced data, be used where the TX and RX operate on several channels close adjacent, i.e. within a certain port bandwidth. In the last case, factory tuning is recommended.
We can tune the filter to any specification within its range at additional cost
