| 10.0-18.0 GHz GaAs Transmitter QFN, 7x7mm August 2007 - Rev 19-Aug-07 U1005-QD Features Integrated Mixer, LO Buffer and Output Amplifier 8 dB Conversion Gain 15 dB Image Rejection +11 dBm P1dB +6 dBm LO Drive Level -12 dBm LO Leakage Power Mimix Broadband's 10.0-18.0 GHz GaAs MMIC transmitter provides +11 dBm output P1dB compression and 15 dB image rejection across the band. This device is an image reject, balanced mixer followed by a two stage output amplifier. The image reject mixer reduces the need for unwanted sideband filtering before the power amplifier. I and Q mixer inputs are provided and an external 90 degree hybrid is required to select the desired sideband. This device comes in a 7x7mm QFN surface mount laminate package which is RoHS compliant. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.

Additionally, a mixer is also required with Vg1=-0.6V. Adjusting Vg1 above or below this value can adversely affect conversion gain, LO/RF isolation and intercept point performance. Gain control can be adjusted by varying Vg2 from 0.0 to -1.2 V with 0.0V providing minimum attenuation and -1.2 V providing maximum attenuation. 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 -0.2V. 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 Tables (TBD) These numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricating foundry.
