406-512 MHz Duplexers
UHF Pass Notch base station duplexer using 3" cavities.
The TPRD-4544 is a compact, pass-reject duplexer for 19" rack mounting, which allows simultaneous operation of a transmitter and receiver, or combiner and receiver sys-
tem, into a common antenna. This duplexer uses four 4-inch cavities to ensure maximum protection from transmitter noise and desensitization. The TPRD-4544 is designed
for systems with a minimum of 5 MHz separation of transmitter and receiver frequencies. Selectivity and insertion loss can be adjusted on each cavity, and a threaded Invar
rod makes field tuning simple if required. This duplexer can also be used to combine 2 transmitters into one antenna, or feed 2 receivers.
