Abstract :
A GaAs MMIC coplanar waveguide amplifier is presented. It is realised on a 100 μm-thick substrate, thus leading to compatibility with microstrip circuits. An amplifier stabilisation technique is presented. It is shown that very good agreement between predictions and measurements may be obtained without any time-expensive bi- (tri-) dimensional electromagnetic simulation. The amplifier gain is ~15 dB at 38 GHz, and return losses are better than -18 dB
