Broadband Lumped-Element GaAs FET Power Amplifiers

Very small (1.5 mm x 2.25 mm) lumped-element matched amplifiers have been developed which cover the 6-12 GHz with 0.3 W and 0.6 W minimum output power levels. Using these matched carriers as building blocks, a 1 W, 7-12 GHz, four-stage amplifier has been demonstrated.
