These lecture notes provide comprehensive coverage of mixer types as used in RF and microwave applications. Three approaches to producing the multiplication of two signals are described: using nonlinear behavior of a diode or transistor, switching, and sampling. Major mixer topologies are also introduced. These notes may be more detailed than what many people are looking for, but they are still worth reading over to gain an understanding of the different mixer strategies.

This app note gives a good understanding of the operation of switching type mixers. "Switching type" refers to the implementation of the mixing operation by using the diode or transistor as a switch that turns the RF signal on and off or inverts its polarity at the LO frequency. Another type of mixer implementation is to bias the diode so that it operates in the square law region so that the output includes the square of the input.

Workbooks from part 1 of the RF Technology Certification program are being gathered here for your reference.
Workbooks contain a summary of formulas for each subject, exercises, suggestions for further reading, and a problem set/quiz. Workbooks posted here are the newest revision being used in the current offering of the program.
Access is restricted to registered users who have completed the certification program.
