we selected QPA9426 as per our power requirement in s-band. our application is half duplex . Can we ground Vref in receive mode to reduce current consumption in receive mode.
Yes, you can set Vref to 0V to reduce current while in receive mode. The current drawn in this condition is listed as leakage current within the data sheet.
thank you for the reply. has to follow sequence for this like ldmos, and Gan amplifiers
