Application Notes:

[1] Biasing -

The device provides variable gain with adjustable bias regulation. For optimum linearity performance, it is

recommended to bias this device at V_D= 4 V with I_D= 90 mA (V_G2 at approximately -0.5 V and V_G1 left open). It is

also recommended to use active biasing to control the drain currents because this gives the most reproducible

results over temperature or RF level variations. 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 -0.5 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.

[2] Bias Arrangement -

For Individual Stage Bias (recommended for saturated applications) each DC pad (V_Dand V_G1,2) needs to have

DC bypass capacitance (~100 - 200 pF) as close to the device as possible. Additional DC bypass capacitance

(~0.01 µF) is also recommended.

[3] Packaging -

MACOM recommends to include a hydrogen getter for situations where this part is being used in a hermetically

sealed package.
