    Overview

    The PE46140 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 3.4–3.8 GHz. The PE46140 also features exceptional linearity, high output port-to-port isolation, and extremely low power consumption relative to competing module solutions.

    Features

        90° phase splitter
        4-bit digital step attenuator, 7.5 dB range, 0.5 dB resolution
        5-bit digital phase shifter, 87.2° range, 2.8° resolution
        High power handling and linearity
        3-bit insertion loss stabilizer (ILS)
        Packaging: 32-lead 6× 6 mm QFN
