We have developped a family of ultra wideband, low power, single supply GaAs normally-off amplifiers. These amplifiers are fabricated with the RTC Limeil digital enhancement mode FET technology. Input and output VSWR's are lower than 2.0 over the entire frequency band. The typical noise figure is 6.2 dB and the single tone -1 dB gain compression is reached at 2 dBm of output power for a linear small signal gain of 8.5 dB. As an application example the combination of multistage amplifiers extends direct frequency counter sensitivities to below -40 dBm.
