Mixer
Mixers are found in virtually all wireless communication sys- tems. They are frequency translating devices that convert input signals from one frequency to another by mixing these signals with another signal of known frequency.
Integrated LNA and Mixer Basics
Basic theory and operation of low noise amplifiers and mixers are presented. Important figures of merits of these two devices such as gain, noise figure, compression point, and third order intercept point are introduced and derived.
Modern Mixer Terms Defined
Today's stringent demands for precise electronic systems places a heavy burden on circuit and systems design engineers. Mini-Circuits provides the most comprehensive database for its RF/MW signal-processing components with its exclusive computer-automated performance data or CAPD and its specification charts which include X and sigma values.
Understanding mixers
Often a mixer data sheet does not specify intercept point, so a rule-of-thumb estimate can easily be made by examining the 1dB compression point. As RF input level is increased, there is a point where the conversion loss will increase.

Improved two tone, third order testing
Two-tone, third-order intermodulation distortion (IM) expresses the degree of non-linearity of an amplifier or mixer. Normally, this parameter is not expressed on data sheets because it is dependent upon operating frequencies, terminating impedance and input levels.
How to select the proper mixer
Mixers are abundant in electronic systems ranging from inexpensive consumer products to sophisticated military hardware.
Frequently asked questions
Frequently asked questions and answers.
Figure of Merit of Mixer Intermod Performance (E Factor)
With increased demand on communication systems, today�s receivers and transmitters need to handle multiple carriers, some wanted and some unwanted. When these carriers arrive at the input of a mixer they combine with each other to generate intermodulation products.
Dual double balanced mixers (HJK, HUD)
What was once considered adequate performance in terms of dynamic range�mixer noise figure at the low-level end of the dynamic range and third-order intercept point (IP3) at the high-level end�is no longer good enough.
