Device Overview

General Description

The MMIQ-0626LSM is a passive GaAs MMIC IQ mixer. This is an ultra-broadband mixer spanning 6 to 26GHz on the RF and LO ports with an IF from DC to 6 GHz. Up to 40 dB of image rejection is available due to the excellent phase and amplitude balance of its on-chip LO quadrature hybrid. Banded performance is possible at lower LO drives. Both surface QFNs and evaluation boards are available.

[1] Amplitude and phase balance measured in a down conversion.

[2][3][4][5][6][7] Measured as an I/Q down converter. (i.e., I and Q powers are not combined)

[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 measured with I and Q ports combined with an external quadrature hybrid coupler in a down conversion.

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

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

Typical Performance Plots

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.
