Driver amplifier for 60 GHz communication systems

A driver amplifier for the ISM band around 60 GHz has been designed and tested. The amplifier has been designed in conjunction with other transceiver sub-systems in the 0.15 mum GaAs pHEMT process of UMS (PH15). The measurements show behaviour very well matched with the extensive circuit and field simulations. The amplifier is approx. 3 times 1.8 mm, consumes 910 mW, has a gain of 22 dB, a P
<sub>-1

dB</sub>
at the output of +14 dBm, and is well matched in the band 60-65 GHz.
