App Note [1] Biasing - The device is operated by biasing VD=4.0V with ID=180 mA. Additionally, a mixer and doubler bias are also required
with VG2=-0.5V. Adjusting Vg2 above or below this value can adversely affect conversion gain, image rejection and intercept point
performance. It is 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.
Typical Application
Mimix Broadband's 30.0-46.0 GHz 40REC0770-QB GaAs MMIC Receiver can be used in saturated radio applications and linear modulation
schemes up to 128 QAM.
