MMIQ-0520L 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 5 to 20GHz 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. Both wire bondable die and connectorized modules are available.

[1][2][3][4] Measured as an I/Q down converter (i.e., I and Q powers are not combined)
[5] 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.
[6] Typical IIP3 is measured with I and Q ports combined with an external quadrature hybrid coupler.
[7][8] Mixer Noise Figure typically measures within 0.5 dB of conversion loss for IF frequencies greater than 5 MHz.
