摘要： A circuit features a balun having an unbalanced input and a balanced output, and a differential coupler having a symmetrical structure about a center axis. The differential coupler has a differential input and a differential output, the differential input being coupled to the balanced output of the balun. An impedance element is coupled to a circuit node of the differential coupler at a point along the center axis. Other embodiments are also described and claimed.

摘要： A device has an RF mixer, an IF mixer module, a single synthesizer, a frequency divider, a single side band mixer and a frequency quadrupler. The single synthesizer generates a signal to the IF mixer module, the frequency divider, and the single side band mixer. The single side band mixer mixes signals from the single synthesizer and the frequency divider. The frequency quadrupler receives the output of the single side band mixer. The RF mixer is coupled to the frequency quadrupler and the IF mixer module.
