BandPass/Reject Duplexer, 220-250MHz


These duplexers are ideal for use with analogue and digital technologies for repeater base station, telemetry, link 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 narrow frequency separations typically used in this frequency band, and that assists in providing protection from co-sited equipment. These duplexers feature excellent continuous operating ratings in a convenient small size.
