Articles on RF Mixers

When calculating the phase noise of a system, there are many considerations. This article from Spectrum Microwave illustrates phase noise calculations of a system and the effects of correlated components verses uncorrelated components.

This Article goes over Mixer Basics, Mixer Terminology, Mixer Topology such as Diode Mixers, FET Mixers, BJT Mixers, Single ended Mixers, Single ended balanced mixers, Double balanced mixers and more.

This Mixers Basics Primer from Marki Microwave sheds light on the "dark art" of microwave mixers and will help you better understand microwave mixers.

Intermodulation distortion suppression is a critical issue in modern military and commercial RF/Microwave systems operating on digital modulation formats which are extremely sensitive to distortion. To meet this hight standards Marki Microwave has developed the Two-Tone-Terminator (T3) mixer family, this primer describes the key operating principles of the T3 mix.

A detailed Gilbert Cell Mixer Design Tutorial with examples.

A downconverter mixer for a broadband access receiver at 40 – 45 GHz with a conversion Loss less than 6 dB and LO power of 10 dBm on GaAs. 

Receivers in support of the continually expanding wireless marketplace rely heavily on improved performance from mixer components. 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. Since modern mixers must provi...

This Technical note from Mini Circuits will help you better understand Mixers - Topics Covered Include: Conversion Loss/Gain, Conversion Compression, Isolation, Dynamic Range, DC Offset, Intercept Point and 2nd and 3rd order Intermodulation.

This note also covers Mixer Measurement techniques for measuring Conversion Loss Measurement, Isolation Measurements, VSWR Measure...

What's a mixer? It's a device that performs the task of frequency conversion, by multiplying two signals (why do you think that the schematic symbol for a mixer is an "X"?) Mixers are needed in most microwave systems because the RF signal is way too high to process its information (for example, looking for a Doppler shift in an X-band radar application, you won&#...

An open collector Mixer design that provides flexibility in setting parameters such as output impedance, conversion gain and linearity.
