Spurs on mixer output
Hi,
If I feed my second mixer into a spectrum analyser, and inject a 44.545MHz LO, with no power to the first IF stage, I see spurs at about 48-50KHz intervals on the mixer output, from 0 to the 455KHz normal output freq. The mixer is an SBL-1. Any ideas as to where these are comming from? Best regards, John |
