RF Mixer spurious analyser.

With this tool the output frequencies of an RF mixer are calculated using the Henderson [see WJ-appnote] model for spurious calculations. RF and LO harmonics levels can be set, the green area is the Intermediate Frequency band.

The numbers above the spectral responses are the orders of the spurs. In the graph you can see that the primary USB and LSB response have a number two, derived from RF and LO 1st order tone.

At present one mixing stage is available, future versions will be extended with more stages to simulate a multiple super-heterodyne designs.
