MMIQ-40100LCH-2_GaAs MMIC mmWave IQ Mixer

Device Overview

General Description

The MMIQ-40100L is a low LO drive, passive GaAs MMIC IQ mixer. This is an ultra-broadband mixer spanning 40 to 100 GHz on the RF and LO ports with an IF from DC to 20 GHz. With a typical image rejection of 30dB from the V through W band, this mixer is an ideal candidate for mmWave I/Q frequency conversion. Both wire bondable die and connectorized modules are available.

Features

RF/LO Frequency Range: 40 - 100 GHz
IF Frequency Range: DC - 20 GHz
I+Q Conversion Loss: 10 dB
Image Rejection: 30 dB

Applications

mmWave Frequency Conversion
Single Sideband and Image Rejection Mixing
IQ Modulation / Demodulation

Typical Performance Plots

Due to difficulty generating strong LO signals at mmWave frequencies LR Isolation is measured with a small signal LO. Isolation will improve with a stronger LO signal. Discontinuity in conversion loss and Image Rejection measurements is due to splitting the measurement into two bands. IIP3 is only measured up to 67GHz due to limitations in measurement setup.
