| 4.5-10.5 GHz GaAs MMIC Receiver October 2007 - Rev 26-Oct-07 R1011-BD Features Integrated LNA, Mixer and LO Buffer Amp 1.6 dB Noise Figure 14.0 dB Conversion Gain BCB Coated Die 100% RF, DC and NF Testing General Description Mimix Broadband's 4.5-10.5 GHz receiver has a noise figure of 1.6 dB and 14.0 dB conversion gain across the band. The device integrates an LNA, image reject mixer and LO buffer amplifier within a single, compact MMIC. The image reject mixer eliminates the need for a bandpass filter after the LNA to remove thermal noise at the image frequency. I and Q mixer outputs are provided and an external 90 degree hybrid is required to select the desired sideband. This device 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. This device is well suited for Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
