RF mixers are indispensable in RF and microwave circuit design, facilitating seamless frequency conversion and ensuring efficient signal transmission. By mastering the basics of RF mixers, …

Choosing the right mixer for the task... What makes a good mixer? Specify performance: Gain, NF, P 1dB, TOI, SFDR, isolation, image rejection. What is a mixer? An ideal mixer is usually …

Properly designed track-and-hold circuit works as sub-sampling mixer. Noise folding leads to large mixer noise figure. Emitter-coupled BJTs work as two limiters. Odd symmetry suppress even …

Mixers have a wide variety of applications in communication systems. The superheterodyne receiver architecture often has several frequency translation stages (IF frequencies) to …

RF Mixers are 3-port active or passive devices. They are designed to yield both, a sum and a difference frequency at a single output port when two distinct input frequencies are inserted …

An RF (or IF) mixer (not to be confused with video and audio mixers) is an active or passive device that converts a signal from one frequency to another. It can either modulate or …
