  • MFG PART #: TPRD-1486 N/F

The Telewave TPRD-1486 duplexers allow simultaneous operation of a transmitter and receiver into a common antenna. These pass-reject duplexers are ideal for use in systems requiring maximum isolation, with close frequency spacing down to 300 kHz. The TPRD-1486 duplexer has three (3) pass-reject cavities each in the transmitter and receiver sections. Selectivity and insertion loss may be adjusted by rotating the calibrated connector loops. Telewave duplexers have 1/4 in aluminum top plates which are fully welded to the aluminum outer conductor. As a result of their superior construction, Telewave 8 in cavity duplexers achieve greater rejection of transmitter noise and spurious radiation, providing excellent receiver protection.
