52-0031-0100 ep04-05-05 dpa2500t dpa4000t anglès.Doc 1 of 2 power module. Due to the high power level required on the output load, the amplifier final stage's structure differs from the design used until now. This is due to the breakdown voltage limit on p-channel mosfet's, with is 200v. This final ...
