Linear amplifier construction data

Like everyone else building Pic-A-Star I'm building my own PA, thinking that a modern approach (and low cost) is necessary I'm planning on building a 40Watt LDMOS amplifier, probably using 4 off RD16HHF1 devices.


Here I have collected relevant data sheets for information, some have been "pinched" of the authors sites... if they want them back let me know!

Transistor data with approx. prices (+VAT in low quantities):

RD06HHF1 £1
RD16HHF1 £3
RD70HHF1 £23
RD100HHF1 ??
RD100HHF1 App note
