The MMIQ-1865S is a high linearity, passive MMIC IQ mixer. This is an ultra-broadband mixer spanning 18 to 65 GHz on the RF and LO ports with an IF from DC to 23 GHz. Up to 35 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.


The electrical specifications apply at TA=+25°C in a 50Ω system. Typical data shown is for a down conversion application with a +21dBm sine wave LO input.  

Min and Max limits apply only to our connectorized units and are guaranteed at TA=+25°C. All bare die are 100% DC tested and visually inspected.

1 Measured as an I/Q down converter. (i.e., I and Q powers are not combined)

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

3 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.

4 Typical IIP3 measured with I and Q ports combined with an external quadrature hybrid coupler.

5 Vector Modulator measured with +30mA DC current applied to the I and Q ports.

6 Measured as I/Q mixer (not IR/SSB mixer). SSB/IR mixers experience additional spurious suppressions.
