It optimizes system performance while reducing manufacturing costs of transmitters that use symmetric or asymmetric power amplifier designs to efficiently process signals with large peak-to-average ratios. This monolithic RFIC integrates a 90° RF splitter, digital phase shifters and a digital step attenuator along with a low voltage CMOS serial interface. It can cover a phase range of 87.2° in 2.8° steps and an attenuation range of 7.5 d B in 0.5 d B steps, while providing excellent phase and amplitude accuracy from 2.3- 2.7...
