The internal DC electrical schematic is given in order to use these pads in a safe way. Vd 50 IN Vds1 Vg 1 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 ( Vg1=Vg2) 25 OUT Vds2 Vg 2 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.
