19.0-26.0 GHz GaAs Receiver
QFN, 7x7 mm
App Note [1] Biasing - The device is operated by separately biasing Vd1 and Vd2 with Vd1=4.0V, 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.
