“The Magic of Mixers:
From Tuner Radio Frequency Receivers to Superheterodyne Receivers”
Speaker: James Hedrick, WB2LKZ
Abstract: The first RF receivers used chained-tuned RF amplifiers all operating at the same frequency. These receivers were difficult to design and even harder to tune. A mixer is a three port circuit that is used to modulate, or demodulate, an RF signal. In this talk we will be exploring how mixers work and how they led to the superhererodyne receivers we use today.
