by Harley Berman Over the past few weeks, we have spent a considerable amount of time here at Marki Microwave studying the performance of our limiters.  Our goal has been to understand how our [...]

By Harley Berman The What and Why of Limiters Limiters are crucial building blocks in Tx/Rx systems and are used to protect sensitive circuity from high power signals.  Take for example a simple [...]

By Cameron Sheth In a typical receiver application, a frequency conversion is performed after filtering and low noise amplification. This frequency conversion can have a significant impact on the [...]

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 Doug Jorgesen In a recent tech note, we summarized 4 Ways to Implement a High Isolation Duplexer for a Transceiver in the specific case where the transmit and receive signals are separated in [...]
