Abstract

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 0.1/spl mu/m /spl Gamma/-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 (P/sub 1dB/). From measurement, the single-ended and the balanced medium power amplifiers show S/sub 21/ gains of 13.14 dB and 12.8 dB, respectively, at 60 GHz. Also, we obtain P/sub 1dB/ of 5.9 dBm and 7.5 dBm at 60 GHz, respectively. The balanced medium power amplifier has better return losses and P/sub 1dB/ than those of the single-ended medium power amplifier within V-band region.
