22TRX0175 18.0-25.0 GHz GaAs MMIC Transmitter

Single Chip Transmitter Integrates Image Reject Mixer, LO Buffer and Output Amplifier

Mimix Broadband's 22TRX0175 is a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) sub-harmonically pumped transmitter, which integrates an image reject sub-harmonic anti-parallel diode mixer followed by a balanced two stage output amplifier and includes an integrated LO buffer amplifier. The image reject mixer eliminates the need for an image bandpass filter after the output amplifier 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 transmitter covers the 18 to 25 GHz frequency bands. The MMIC device has 20 dBm output third order intercept (OIP3), 15 dB image rejection across the band and 2 dBm LO drive level.

This transmitter is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications.

Mimix performs 100% on-wafer RF and DC testing on the 22TRX0175, as well as 100% visual inspection to MIL-STD-883 method 2010. The chip also has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process.

Engineering samples are available today from stock and production quantities are available 6-10 weeks after order processing.
