Abstract :
A 5.25 GHz GaAs PHEMT power amplifier for 802.11a application has been realized in the OMMIC 0.2 μm AlGaAs/InGaAs/GaAs PHEMT process. To guarantee the PHEMT unconditionally stable, a combined stabilizing circuit is used. Under a single supply voltage of +3.5V, this power amplifier exhibits linear output power of 24.8 dBm (P1dB), small signal gain of 25.6 dB and the power added efficiency (PAE) of 22% at P1dB. The die size is only 1.5 mm×1.0 mm.
