APPLICATION NOTES & TECH NOTES
-
Using The MMIQ-0218 As A Vector Modulator
The proper way to apply a DC current to the mixer is through a bias tee, allowing the high-frequency output from the mixer to absorb rather than reflect back into the mixer, potentially causing ripple or other degradation to the performance of the IQ mixer as a vector modulator.
-
LO To RF Isolations: Why A 10dB Buffer Is Best
The LO to RF isolation of a mixer is a critical performance specification in most broadband applications. LO feedthrough can not only contaminate a system, but the noise fed from the LO path can degrade a system’s noise figure.
-
Near-Zero Spike Leakage Of Marki Schottky Diode Limiters
GaAs Schottky diodes in Marki Microwave limiters are created on a THz process, allowing them to switch on and off at incredibly high speeds. This, combined with novel circuit designs, allows us to offer devices with virtually zero spike leakage and nearly immediate recovery times.
-
Recovery Time Of GaAs Schottky Diode Limiters
Limiters are crucial building blocks in Tx/Rx systems and are used to protect sensitive circuity from high power signals. System designers commonly place a limiter between the antenna and LNA, which protects the sensitive LNA and Rx signal chain.

How It’s Made: Optimal SMT Launches For QFN Packaged MMIC Filters
In this tech note, we will break down surface-mount packaging parasitic sources and present solutions to combat these undesirable parasitics.
WHITEPAPERS
-
In this white paper, a novel, multi-octave differential power divider is described. The power divider circuit is based on a new kind of Magic-T circuit composed of a balun and two parallel coupled transmission lines.
-
The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.
-
This application note introduces IQ, single sideband (SSB), and image reject (IR) mixers in both theory and practice. We will discuss basic applications, their concepts, and practical considerations in their selection and use.
-
This Mixer Basics Primer intends to shed light on the “dark art” of microwave mixers to help customers better understand, select, and ultimately use Marki Microwave mixers.
-
Baluns have long been ubiquitous in low frequency audio, video, and antenna driving applications. The need for high speed, low noise data transfer has driven the advancement of the balun to higher frequencies and superior performance.
