Abstract :
A two-stage PHEMT MMIC low noise amplifier with a very low noise figure as low as 0.76 dB and gain >16 dB at 5.4 GHz has been implemented using a minimum input matching network. It is believed that the noise figure of 0.76 dB is the best result ever reported to date from MMIC LNAs over this frequency range. This is attributed to the low noise performance of the PHEMT transistor and minimised parasitic resistance of the input matching network
