4.0-11.0 GHz GaAs MMIC Buffer Amplifier, QFN B1007-QT Page 5 of 6 App Note [1] Biasing - The device provides variable gain with adjustable bias regulation. For optimum linearity performance, it is recommended to bias this device at Vd=4V with Id=90 mA. It is also recommended to use active biasing to control the drain currents because this gives the most reproducible results over temperature or RF level variations. 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 -0.5V. 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 Graphs These numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricating foundry.
