In this work, balanced medium power amplifiers for 60 GHz wireless LAN application were designed and fabricated. The single-ended and the balanced medium power amplifier on MIMIC technology were designed using 0.1μm Γ-gate GaAs PHEMT and CPW library. We compared the single-ended medium power amplifier on the balanced medium power amplifier of S-parameter and 1 dB gain compression point (P1dB). From measurement, the single-ended and the balanced medium power amplifiers show S21 gains of 13.14 dB and 12.8 dB, respectively, at 60 GHz. Also, we obtain P1dB of 5.9 dBm and 7.5 dBm at 60 GHz, respectively. The balanced medium power amplifier has better return losses and P1dB than those of the single-ended medium power amplifier within V-band region.
