bipolar PushPull vs MOSFET ?

Hi,

Someboby know how can i do to have the same fonction than a NPN PNP push pull design with N&P channel MOSFET (4Mhz input signal) ?

Regards

SELECT DEVICES.
see the application notes.
search google for "push pull amplifier" mosfet .pdf
look for similar examples.
start with www.irf.com

check boylestad. i think that the circuit is given in the book u need. otherwise there are a lot of books on elektroda search for RF CIRCUIT DESIGN
