The MM1-0424S from Marki Microwave is a passive GaAs double balanced MMIC mixer with an RF/LO frequency from 4.5 GHz to 24 GHz and IF frequency from DC to 4 GHz. The mixer features an excellent conversion loss, isolation and spurious performance across its broad bandwidth. It is available as a wire bondable chip that measures 0.058" x 0.046" x 0.004" or as an SMA connectorized module. Like most Marki Microwave products this model too has a non-linear software model available with the Marki PDK for Microwave office.
