Power Amplifier
App Note [1] Biasing
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 -0.9V. 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 -
All the drain or gate pad DC bypass capacitors (~100-200 pF) can be combined. Additional DC bypass capacitance (~0.01 uF) is also
recommended to all DC or combination (if gate or drains are tied together) of DC bias pads.
