Chip Biasing
This chip is a two stage amplifier, and flexibility is provided by the access to number of pads.
The internal DC electrical schematic is given in order to use these pads in a safe way.

The two requirements are :
N°1 : Not exceed Vds = 3.5Volt
( internal Drain to Source voltage ).
N°2 : Not biased in such a way that Vgs becomes positive.
( internal Gate to Source voltage )
We propose two standard biasing :
Low Noise and low consumption :
Vd = 3.5V and Id = 30mA.
Low Noise and high output power :
Vd = 4.0V and Id = 45mA.( A separate acces to
the gate voltages of the first and the output stage is provided. Nominal bias is obtained for a
typical current of 30mA for the output stage and 15 mA for the first stage. The first step to
bias the amplifier is to tune the Vg1 =-1V and Vg2 to drive 30mA for the full amplifier. Then
Vg1 is reduced to obtain 45 mA of current through the amplifier.
