The,RA30H4452M,is,a,30-watt,RF,MOSFET
Amplifier,Module,for, -volt
mobile,radios,that,operate,in,the,440-,to,520-MHz,range.
The,battery,can,be,connected,directly
to,the,drain,of,the,enhancement-mode,MOSFET,transistors.
With,a,gate,voltage,around,4V
(minimum),,output,power,and,drain,current,increases,substantially.,The
nominal,output,power,becomes
available,at, ,(typical),and,5V,(maximum).,At
VGG=5V,,the,typical,gate,current,is,1
mA.
This,module,is,designed,for
non-linear,FM,modulation,,but,may,also,be,used,for,linear,modulation,by,setting,the
drain,quiescent,current,with
the,gate,voltage,and,controlling,theoutput,power,with
the,input,power.
