27TRX0357

Mimix Broadband's 27.0-36.0 GHz GaAs MMIC transmitter has a +20.0 dBm output third order intercept and 20.0 dB image rejection across the band. 27TRX0357 is an image reject sub-harmonic anti-parallel diode mixer followed by a three stage output amplifier and includes an integrated LO buffer amplifier. The image reject mixer reduces the need for unwanted sideband filtering before the power amplifier. The use of a sub-harmonic mixer makes the provision of the LO easier than for fundamental mixers at these frequencies. I and Q mixer inputs are provided and an external 90 degree hybrid is required to select the desired sideband. This MMIC uses Mimix Broadband's 0.15 m GaAs PHEMT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity. 27TRX0357 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. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
