The PE46120 is a HaRP™ technology-enhanced monolithic phase and amplitude controller (MPAC)–Doherty device designed for precise phase and amplitude control of two independent RF paths. 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 dB in 0.5 dB steps, while providing excellent phase and amplitude accuracy from 1.8–2.2 GHz. The PE46120 also features exceptional linearity, high output port-to-port isolation and extremely low power consumption relative to competing module solutions.
