It is more effective to use bandpass duplexers, which cavities are tuned to pass receiver frequencies (in receiver circuit) and transmitter frequencies (in transmitter circuit), instead of band pass-reject duplexers at considerable receiving and transmission frequency separation. Having higher filtration capability, duplexer DPF5-4(6)V will handle out-of-band emission attenuation better. These duplexers classical application is two militia radio stations 148 and 172 MHz combination. In the last case triple-cavity duplexer DPF5-3V is applicable.
