The Telewave TPRD-1554 duplexer allows simultaneous operation of a transmitter and receiver into a common antenna. This pass-reject duplexer is ideal for systems with very close frequency spacing.

The TPRD-1554 has two pass-reject cavities in the transmitter and receiver sections. This duplexer is designed for transmitters and receivers with frequency spacing of 600 KHz or more.

Because of their superior construction, this Telewave 5” cavity duplexer achieves greater rejection of transmitter noise and spurious radiation, providing excellent receiver protection. Telewave duplexers have ¼”aluminum top plates which are fully welded to the aluminum outer conductor. Silver-plated tuners, beryllium copper finger stock contactors and threaded Invar rods assure maximum temperature stability, higher “Q”, and many years of trouble-free operation. Selectivity and insertion loss may be adjusted by rotating the calibrated connector loops.
