V-band CPW balanced medium power amplifier for 60 GHz wireless LAN application

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.
