Tips for Simulating a Transmit Mixer in SpectreRF

Some typical questions that I receive from newer SpectreRF users are: How do I simulate a transmit mixer? How do I look at both upper and lower sidebands? How do I set up my simulation for PAC and Pnoise? When I plot my data, how do the indexes correspond...  Read More »
