Abstract
This paper presents the design and fabrication of two-stage medium power amplifier (MPA) using 0.5 mum GaAs PHEMT technology for the wireless LAN applications. The die size of this amplifier is only 1.7 mm times 0.85 mm. At a supply voltage of 5.0 V and 5.8 GHz operating frequency, a 2-stage MPA achieves a linear gain (S21) of 16.39 dB, P1 dB of 20.18 dBm, power gain of 15.15 dB and the PAE of 25.29%.
