XX1000-QT provides good performance at reduced bias with Vss=-2.0V and Iss=25mA. Maximum output power is achieved with Vss=-5.0V and Iss=50mA. Separate biasing is recommended if the doubler is to be used at high levels of saturation, where gate rectification will alter the effective gate control voltage. 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 voltages needed to do this are Vg1=-0.6V and Vg2=0.0V. 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.
