Monolithic phase and amplitude controller features a 90 degree phase splitter

Peregrine's PE46130, stocked by Digi-Key, 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 optimises 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 degree 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 degrees in 2.8 degree steps and an attenuation range of 7.5dB in 0.5dB steps while providing excellent phase and amplitude accuracy from 2.3GHz to 2.7GHz.
