Abstract :
For application at frequencies around 140 GHz, a solid-state amplifier with variable output matching was developed. Its output matching network makes use of a capacitively loaded shunt switch in series and a shunt switch in parallel. By variation of the control voltages of the series and parallel switches, the output impedance continuously can be changed in a wide range. This makes the circuit very versatile. It can be applied to runtime tuning of the amplifier and transistor model verification.
