Using the MMIQ-0218 as a Vector Modulator
by Doug Jorgesen A high frequency tone or carrier is defined by two parameters: the magnitude and phase. In many applications it is required to modify the magnitude and phase of a carrier to an [...]
Why SOI? Marki Enters the Silicon World
by Brian Baxter If you attended IMS this year you saw an important product announcement, in a completely new category, from Marki: a switch. A switch doesn’t seem like a big deal, but this switch [...]
An Introduction to Microwave Amplifiers Part 2: Figures of Merit
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 [...]
Application Examples for MQS and MQH Quad Hybrid MMIC die
by Douglas Grosch Quadrature hybrids are useful for countless applications, including balanced amplifiers, IQ/IR/SSB mixers, reflectionless filters, and reflective phase shifters. Marki [...]

4 Ways to Implement a High Isolation Duplexer for a Transceiver
by Harley Berman In a transceiver design, it can be advantageous to use a single antenna for both transmitting and receiving signals instead of two separate antennas. The process of [...]
The Self-Alignment of Reflowed Surface Mount Components
Misplacement of surface mount components by a pick and place machine or a human assembler can be inconvenient. Fortunately, surface mount components seem to magically (and conveniently) align [...]
Repeatability of T3 Mixers and Other Handmade Microwave Components in Six Charts
T3 mixers are the highest dynamic range mixer available. They are also handbuilt parts, subject to unit to unit and lot to lot variability. In this blog post we attempt to quantify that [...]
