Abstract(in English) | At Ku-Band,an internally matched high power AlGaAs, InGaAs HJFET amplifier has been successfully developed.Large signal load-pull measurements were performed on a 1.05mm gate periphery device to obtain optimal power and optimal PAE.The unit 1.05mm HJFET chip has exhibited an output power of 29.1dBm(O.813W),with 13.4dB linear gain and 60% PAE with reasonable linearity.A 8.4mm HJFET chip which consists of 8 unit FETs has been selected as the building block of the power amplifier.The amplifier has demonstrated an output power of 37.5dBm(5.6W),with 13dB linear gain and 56% PAE with a 7V drain bias.When the drain bias was increased to 8V,it delivered 38.2dBm(6.6W)output power with 12.5dB linear gain and 50% PAE with excellent linearity. |
