Sinclair developed the Q2330E design coupled with our Res-Lok™modular construction resulting in an extremely versatile duplexersoffering exceptional performance. The Q2330E design provides aquasi-bandpass response, resulting in suppression of spurious andsideband transmitter noise between and adjacent to the duplexfrequencies. Coupled with carefully temperature compensated componentsthis series of duplexers ensures performance stability at very lowfrequency separations and insertion loss values.

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

The TPRD-1556 has three passreject cavities in the transmitter andreceiver sections. This duplexer is designed for transmitters andreceivers with frequency spacing of 400 KHz or more.

Vari-Notch® duplexers are used to provide simultaneousoperation of a transmitter and receiver (ortwo transmitters) which are at different frequencieswhile connected to a common antenna. Theseduplexers are frequently used in radio repeatersystems.

144-190 MHz 6-Cav Pass/Notch Base Duplexer, .5 MHz Spacing"

The Telewave TPRD-1544F allows simultaneous operation of atransmitter and receiver into a common antenna. This pass-rejectduplexer utilizes folded four-inch cavities to achieve high "Q" in acompact size.

Telewave models TPRD-1584 and TPRD-1586 allow simultaneous operationof a transmitter and receiver into a common antenna. ThesePass-Reject duplexers are an ideal choice for systems requiringmaximum isolation, with close frequency spacing down to 300 KHz.

The TPRD-1544C and 1544CM produce high performance in a compactdesign for the 148-174 MHz VHF band. These duplexers are less than30% of the size of earlier models, and deliver greater isolation andpower handling.
