About this item
Pass-Reject Base Station Duplexer – 144-174 MHz
TPRD-1554
- Pass-Reject Base Station Duplexer
- 144-174 MHz
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.
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.
