Amplifier, Buffer
37 - 40 GHz
Rev. V4
App Note [1] Biasing - It is recommended to bias the amplifier with VD = 4 V and ID_TOTAL = 250 mA. 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 -0.3 V. 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
(100 pF/10 nF/1 µF) as close to the package as possible.
