Q2330E
Q2330E Duplexer, Q-Circuit, high isolation, rack mount, N female
• Six-cavity provides 85 dB isolation
• Res-Lok design reduces inter-cavity cabling and losses
• Provides up to 85 dB isolation at frequency separation of 500 KHz
Sinclair developed the Q2330E design coupled with our Res-Lok™ modular
construction resulting in an extremely versatile duplexers offering exceptional
performance. The Q2330E 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.
