Above — For those who have trouble visualizing mixer math, this frequency domain sweep tells the story of mixing 2 frequencies in a diode ring.
This spring/summer I watched yet another YouTube video stating that mixing the RF + LO results in 2 frequencies. I wish it were true! In general, we can describe mixer output frequencies with the equation:
IF (output freq) = N x LO port freq +/- M x RF port freq — where N and M = integers such as 1, 2, 3 ….
Above — 2 tones from the output port of my 6 dB hybrid combiner into my DSO
Above — Vishay MLCC HF bypass caps. Summer is the time to buy parts for Fall-Winter building.
Above — Great, ten NE612 ICs.
That’s all. Thanks.
