Used Sinclair Q2220E Duplexer, Q-Circuit, Res-Lok, 4 cavity, rack mount, 138-174 MHz *** Frequencies noted in the photos may not be accurate *** *** Buyer is responsible of tuning of item *** From the Manufacturer: Description 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.
