This figure shows the microphotograph of the fabricated ultra-wideband high power amplifier with a size of 5.5 mm x 5.0 mm. The amplifier was demonstrated an average saturated output power of 15-W with good return losses over a frequency range of 6 GHz to 18 GHz. This chip will be a good candidate for realizing phased array jammer systems. See page 972.
