Abstract

For mobile terminals using antenna diversity, a prototype monolithic integrated triple input low noise amplifier (LNA) with diversity function has been realized. The diversity LNA has more than 10 dB gain and less than 4 dB noise figure from 4 to 5 GHz. For comparison, a single LNA was fabricated on the same wafer showing very similar performance. The chip area is reduced by more than 30% and the power consumption by 50% compared to a multichip LNA with a switch
