【摘要】A 4–9 GHz wideband high power amplifier is designed and fabricated,which has demonstrated saturated output power of 10 W covering 6–8 GHz band,and above 6 W over the other band. This PA module uses a bal- ance configuration,and presents power gain of 7.3 ± 0.9 dB over the whole 4–9 GHz band and 39% power-added efficiency (PAE) at 8 GHz. Both the input and output VSWR are also excellent,which are bellow –10 dB.
