U1003-QD

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

Mimix Broadband's 19.0-26.0 GHz GaAs MMIC transmitter has a +20.0 dBm output third order intercept and 15.0 dB image rejection across the band. This U1003-QD 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 U1003-QD 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 U1003-QD device comes in a 7x7mm QFN surface mount laminate package that is RoHS compliant. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
