Abstract
We report on the development of a very compact 60 GHz high efficiency power amplifier operated at a bias voltage of only 3 V with a measured saturated output power of 200 mW. Due to the small chip size of 2 x 1 mm2 the amplifier has a power density of 100 mW/mm2 which is 80 per cent higher than the best results reported to date at this frequency. The combination of high output power and reduced chip size together with a state-of-the-art power added efficiency (PAE) of 21 per cent can be attributed to the use of 0. 15 mu m T-gate PHEMTs in combination with coplanar waveguide technology.
