#200: T/R Switch w/ PIN Diodes and Lumped Element Quarter-wavelength transmission line

The notes for this video clip can be located below:

This video clip explains and also shows a straightforward, single-band, low-power, digital send/ obtain button making use of PIN diodes an a quarter-wavelength RF transmission line. An abided component matching of the 1/4 wavelength line is gone over and also developed right into a PIN diode based T/R button, and also the procedure is shown on the oscilloscope. This video clip builds on a couple of previous video clips, detailed right here:
