Hi 902, Understand about the sideband noise, but I figured at a MHz away, it probably wouldn't be an issue. Getting the same performance out of both sides of the duplexer ... about 102dB notch & 1.5dB attenuation.
Using RG142 for all interconnects, except from TX/RX to duplexer, and those are RG-214. Guess I could hookup a signal generator with a -50dBm signal into the RX, and measure it at the input with a high impedance probe hooked to the spectrum analyzer. Take that measurement, and then hook up the duplexer & key it up. Check the measurement again & see if it's the same, or more. Thanks, Tim
