Hi all,

I am generating a PWM signal with an xmos (gpio) device. Signal has
following characteristics ;

Frequency ; 50 MHz
duty cycle ; %50
rise/fall times ; ~sub-ns
Amplitude ; 3.3v or TTL (I can choose)

it's all fine but I need a max amplitude of 10-11 volts. Actually we are
not sure exactly the required voltage range thus I am planning to do it
adjustable between 5V-12V.

I obviously need a very fast transistor but haven't been on the analog
stage for a long time. I think a well chosen rf-transistor might do the
trick.

Any suggestions or references ?
Thank you.

Y.
