| 17.0-25.0 GHz GaAs Receiver QFN, 7x7 mm August 2007 - Rev 30-Aug-07 Features Sub-harmonic Receiver Integrated LNA, LO Buffer, Image Reject Mixer 7x7 mm, QFN +2.0 dBm LO Drive Level 2.5 dB Noise Figure 20.0 dB Image Rejection 100% On-Wafer RF, DC and Noise Figure Testing Mimix Broadband's 17.0-25.0 GHz GaAs packaged receiver has a noise figure of 2.5 dB and 20.0 dB image rejection across the band. This device is a two stage balanced LNA followed by an image reject sub-harmonic anti-parallel diode mixer and includes an integrated LO buffer amplifer. The image reject mixer eliminates the need for a bandpass filter after the LNA to remove thermal noise at the image frequency. 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 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. The device comes in a 7x7 mm QFN Surface Mount Laminate Package offering excellent RF and thermal properties and is RoHS compliant. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.

It is also recommended to use active biasing to keep the currents constant as the RF power and temperature vary; this gives the most reproducible results. Depending on the supply voltage available and the power dissipation constraints, the bias circuit may be a single transistor or a low power operational amplifier, with a low value resistor in series with the drain supply used to sense the current. The gate of the pHEMT is controlled to maintain correct drain current and thus drain voltage. The typical gate voltage needed to do this is -0.3V. Typically the gate is protected with Silicon diodes to limit the applied voltage. Also, make sure to sequence the applied voltage to ensure negative gate bias is available before applying the positive drain supply. MTTF MTTF is calculated from accelerated life-time data of single devices and assumes an isothermal back-plate.
