Pass/Reject Duplexer
Product Description
The Telewave Model TPRD-4744 duplexer allow simultaneous operation of a transmitter and receiver into a common antenna. These pass-rejectduplexers are ideal for systems with very close frequency spacing of 1 MHz or more. The Telewave TPRD-4744 has two -wave pass-reject cavities in thetransmitter and receiver sections. Because of their superior construction, these Telewave 5 cavity duplexers achieve greater rejection of transmitter spuriousand noise radiation, providing excellent receiver protection. All duplexers are tuned and tested with customer-specified frequencies prior to shipping. Iffrequency changes are required, the positive locking mechanism allows for easy field tuning by rotating the threaded Invar rod
