New MPAC for precise phase and amplitude control of two independent RF paths

Now stocked by Digi-Key, Peregrine's PE46120 is a HaRP technology-enhanced monolithic phase and amplitude controller (MPAC) designed for precise phase and amplitude control of two independent RF paths. The device 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. The 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 in 2.8 degrees steps and an attenuation range of 7.5dB in 0.5dB steps while providing high phase and amplitude accuracy from 1.8 to 2.2GHz. The PE46120 also features exceptional linearity, high output port-to-port isolation and extremely low power consumption relative to competing module solutions.
