250W VHF Band Pass / Band Reject Duplexer, 148-174MHz

DP1417-3442-31

These duplexers are ideal for use with analogue and digital technologies for high power repeater base stations, telemetry, links and other applications. The high-selectivity resonators coupled together in a band-pass / band-reject configuration provide a pseudo-bandpass response that can cater for the very narrow frequency separations typically used in this frequency band, and that assists in providing protection from co-sited equipment. Excellent tuning stability is maintained across the guaranteed extended temperature range. The black painted finish provides excellent corrosion protection, and the convenient form factor and mounting holes allow the unit to be deployed into a range of installation configurations
