Bandpass filter 380-470MHz BPF70/3

BPF 70/3 N | Amphenol Procom
The BPF70/3 uses three internally coupled 1/4 resonators and is designed for the 70cm band (380-470MHz). It can be used as a pre-selector to protect a receiver from out-of-band interference or to reduce spurious output from a transmitter up to 50W. The rugged extruded aluminum housing, combined with a brass chassis and Teflon insulation, ensures reliability from -30°C to +60°C, while the vinyl covering prevents corrosion.
