Device Overview

General Description

MMIQ-1040L is a low LO drive, passive GaAs MMIC IQ mixer that operates down to an unrivaled +3 dBm LO drive level. This is an ultra-broadband mixer spanning 10 to 40 GHz on the RF and LO ports with an IF from DC to 12 GHz. Up to 30 dB of image rejection is available due to the excellent phase and amplitude balance of its on-chip LO quadrature hybrid. Both wire bondable die and connectorized modules are available.

Port Configuration and Functions

Port Diagram

The mixer may be operated as either a downconverter or an upconverter. Use of the RF or IF as the input or output port will depend on the application. See Application Information for input and output port configuration for common applications.

[1][2][3][4][5][6] Measured as an I/Q down converter. (i.e., I and Q powers are not combined)

[7][8] Image Rejection and Single sideband performance plots are defined by the upper sideband (USB) or lower sideband (LSB) with respect to the LO signal. Plots are defined by which sideband is selected by the external IF quadrature hybrid.

[9] Typical IIP3 is measured with I and Q ports combined with an external IF quadrature hybrid coupler.

[10][11] Mixer Noise Figure typically measures within 0.5 dB of conversion loss for IF frequencies greater than 5 MHz.

Typical Performance Plots

The test conditions and frequency plan below applies to all following sections, unless otherwise specified.

I output means that the IF output signal is measured at the I port of the mixer and the Q port is loaded. Q output means the IF output signal is measured at the Q port of the mixer while the I port is loaded.
