App Note [1] Biasing - As shown in the bonding diagram, this device is operated by separately biasing Vd1 and Vd2 with
Vd1=3.5V, Id1=130mA and Vd2=4.0V, Id2=116mA. 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 pad (Vd1,2 and Vg1,2) needs to have DC bypass capacitance (~100-200 pF) as close to the device
as possible. Additional DC bypass capacitance (~0.01 uF) is also recommended.
