Mixers and Frequency Conversion

Author: 

Microwave Journal Magazine

Frequency conversion is a critical function in all wireless systems. A key component used to accomplish this is the mixer. Designers need to understand different mixer topologies and specifications in order to meet their system requirements. This webinar provides a brief overview of frequency conversion and introduces the mixer as the component used to accomplish this function.

Mixer Lectures

Author: 

S. Long, UCSB

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.

Mixer Basics Primer

Ferenc Marki & Christopher Marki, Ph.D.

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.
