App Note [1] Biasing - It is recommended to bias the amplifier with Vd=4.0V and Id=600mA. 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.
App Note [2] Bias Arrangement -
Each DC pin (Vd and Vg) needs to have DC bypass capacitance (10 nF/1 uF) as close to the package as possible.
