@FvM The IGS(gate supply current) for Power amplifier is 10mA(from datasheet) There is no excessive current drawn from VGS. I need to check which voltage is dropping first
@Carry for cents bazar Thanks for the reply
The biasing/sequence module **broken link removed** needs VGS= -8V hence I am generating -8V from MAX765ESA+(output current 250mA). For VDS(Drain supply voltage) I am feeding externally from RPS(Regulated Power Supply).
We have designed a custom board using the **broken link removed**. We are Using this custom board to provide Biasing voltages to the QPA1022 Amplifier.
We tested the custom board with the following set-ups:-
SETUP-1:- WITH NO LOAD(Power amplifier)
Under this setup Gate voltage is being generated...
