PLSK vs. DPSK in Four Wave Mixing Crosstalk
Notes on PLSK vs. DPSK in Four Wave Mixing Crosstalk.
Mixers basic
A Mixer is an analogue device that can multiply two signals together and also provides the difference of the two signals. They are composed of a non-linear device (a diode or a transistor) and passive couplers devices to inject the input mixing signals into the non-linear device that will perform the mixing.
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.
