"D C TO 8 GHz GaAs Normally-Off Amplifiers"

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.
