35.0-42.0 GHz GaAs MMIC Transmitter U1006-BD December 2007 - Rev 12-Dec-07 Features Sub-harmonic Transmitter Integrated Mixer, LO Doubler/Buffer & Output Amplifier +17.0 dBm Output Third Order Intercept (OIP3) 4.0 dBm LO Drive Level 3.0 dB Conversion Gain 100% On-Wafer RF and DC Testing 100% Visual Inspection to MIL-STD-883 Method 2010 General Description Mimix Broadband’s 35.0-42.0 GHz GaAs transmitter is an integrated multifunction chip which provides 25 dB of linear gain control across the band. The MMIC has a +17.0 dBm output third order intercept across the band.This device is a balanced, resistive pHEMT mixer followed by a series of cascaded gain and attenuator stages. The device also includes an integrated LO doubler and LO buffer amplifier which make 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 µm GaAs PHEMT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity. The 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 device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
