1. Top 7 Ways to Create a Quadrature (90˚) Phase Shift We’ve talked a lot about IQ mixers in the last few posts, about their theoretical underpinnings and applications as a phase detector and [...]

This is part 2 of this series. Part 1, Applications, is available here. In this article we discuss amplifier figures of merit, and along the way you will hopefully develop an intuition for how to [...]

by Robert Maurer AMM-6702UC5 offers positive only, +5V operation of the AMM-6702UC amplifier Supply voltage suppression of 100 dB The voltage rectifier circuit and BoM are shown below so [...]

by Jacob Trevithick Phase noise is critical to systems, like Electronic Warfare and 5G Communications, requiring precise frequency stability. Oscillators are typically the determining factor in [...]

Modern battlefields are awash in electronic signals from radars, jammers, and radio communications. Therefore, high linearity EW receivers for applications such as Radar Warning Receivers, [...]

This is a (virtually) math-free introduction to microwave amplifiers from an applications standpoint. There are many references available for the aspiring amplifier designer; this series of posts [...]

Frequency multipliers are used to generate higher harmonics from an input sinusoid.  In particular, the job of the doubler is to output only the 2nd harmonic.  Invariably, the fundamental tone [...]
