Q2220E VHF Duplexer, Q-Circuit, rack mount, N female

• Four cavity duplexer with 70 dB of isolation

• Only 1.5 dB insertion loss at 500 KHz separation

• Isolation of 80 dB at 3 MHz spacing typical

Sinclair developed the Q2220E design coupled with our Res-Lok™ modular

construction resulting in an extremely versatile duplexer offering exceptional

performance. The Q2220E design provides a quasi-bandpass response, resulting in

suppression of spurious and sideband transmitter noise between and adjacent to the

duplex frequencies. Coupled with carefully temperature compensated components

this series of duplexers ensures performance stability at very low frequency

separations and insertion loss values.

• Res-Lok™ modular construction offers a variety of mounting options. The multi position

brackets supplied with each duplexer allow easy rack, wall or floor mounting to suit system

and equipment room limitations. A variety of system-specific configurations is available in

the 138-174 MHz frequency range.
