Abstract :
A simple picosecond pulse shaping and compression circuit with a 0.3 mu m GaAs MESFET is reported. A 2 V amplitude negative pulse with full width at half maximum of approximately 30 ps is obtained at the 50 Omega output. The observed pulse shaping and the pulse width compression factor GPW>or=2.6 show the beneficial influence of the strongly nonlinear regime of the FET on the performances. The results and further pulse narrowing are discussed using time domain simulations of the pulser.
