Tayloe-Style Upconverting RF Mixer Transmitter Demonstration

This video shows a breadboard demonstration of using a Tayloe RF mixer to upconvert IQ data and transmit a radio signal to a receiver. It builds on two videos I made about Tayloe mixers and radio receivers.

Note: Would be a good idea to add a simple low-pass filter to the transmitter output. See this video:    • Видео
