(3) Channel temperature affects a device's MTTF. It is recommended to keep channel temperature as low as possible for maximum life.

Mimix Broadband's 18.0-25.0 GHz GaAs MMIC transmitter has a +20.0 dBm output third order intercept and 15.0 dB image rejection across the band. This U1002-BD device is 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 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. The U1002-BD chip 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 U1002-BD device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
