Product Description

The Telewave Model TPRD-1456 Pass Reject Duplexer 118-148 MHz, allows simultaneous operation of a transmitter and receiver in to acommon antenna. These pass-reject duplexers are ideal for systems with very close frequency spacing.The TPRD-1456 has three pass- reject cavities in the transmitter and receiver sections. This duplexer is designed for transmitters and receivers with frequency spacing of 400 KHz or more. Because of their superior construction, these Telewave 5” cavity duplexers achieve greater TPRD-1456 rejection of transmitter spurious and noise radiation, providing excellent receiver protection.

Telewave duplexers have 1⁄4” 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. (See next page for typical response curves.) All duplexers are tuned and tested with customer-specified frequencies prior to shipping. If frequency changes are required, the positive locking mechanism allows for easy field tuning by rotating the threaded Invar rod.

The optional TBC-40 indoor cabinet completely encloses the duplexer, and protects it from dust, dirt and tampering. All connections are accessible from the top of the cabinet.
