i want to design class E power Amlifier for 900 Mhz application , and i want to know where to start ,
so please recommend a book , or paper to begin with
and i saw most of the class E amps use LDMOS or CMOS , or HBT , what about biploar devices are they used in this class
and also i want to ask how to select the bias point of the gate or the base
The latter case: no any bias as much as a Class AB bias, only just a little (say 0.2-0.3V DC, definitely not causing any collector current) to easy the RF drive at 900MHz, this helps the obviously not so rapid rise time of the drive pulse.
