Buffer Amplifier

App Note [1] Biasing
- As shown in the bonding diagram, this device can be operated with all four stages in parallel, and can be biased for
low noise performance or high power performance. Low noise bias is nominally Vd=3V, Id=110mA. More controlled performance will be
obtained by separately biasing Vd1 and Vd2 each at 3.0V, 55mA. Power bias may be as high as Vd=5.5V, Id=220mA with all stages in parallel,
or most controlled performance will be obtained by separately biasing Vd1 and Vd2 each at 5.5V, 110mA. 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 -0.5V. 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
-
For Parallel Stage Bias (Recommended for general applications) -- The same as Individual Stage Bias but 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.
For Individual Stage Bias (Recommended for Saturated Applications) -- 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.
