SINCLAIR's Q2220E 132 – 174 MHz duplexer. pass-Notch type. 4 cavity. 350 W. 0.5 MHz minimum separation 1.5 dB loss. N Female connector. * or field tune
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 the suppression of spurious and sideband transmitter noise between and adjacent to the duplex frequencies. Coupled with careful temperature-compensated components this series of duplexers ensures performance stability at very low-frequency separations and insertion loss values.
