Q2220E
Q2220E 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.
