Mimix Broadband introduces of a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) sub-harmonically pumped receiver, which integrates a two stage balanced LNA followed by an image reject sub-harmonic anti-parallel diode mixer and includes an integrated LO buffer amplifier. The image reject mixer eliminates the need for a bandpass filter after the LNA to remove thermal noise at the image frequency. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, this receiver covers the 18 to 25 GHz frequency bands. The MMIC device has noise figure of 2.5 dB, 15.0 dB image rejection across the band, and 2.0 dBm LO drive level. This receiver, 22REC0174, is suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications.
