Part 2 of the Mixer Mini-Series.
Nick M0NTV explores the design and construction of a Diplexer for the IF port of a Double Balanced Diode Ring Mixer.
Part 1 is here: • 20 - Double Balanced Diode Ring Mixer
In terms of DESIGNING the diplexer I actually started with the Diplexer Calculator (Bridged Tee) at: https://www.changpuak.ch/electronics/...
I then took these values and also modelled the design in LTSpice. When it came to physically building it I tested the series resonant filter and the parallel resonant filters separately first of all with an S21 sweep on the NanoVNA. This is how I usually test all my filters these days.
