Product Description
The PE46120 is a HaRP™ technology-enhanced monolithic phase and amplitude controller (MPAC) 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. It is offered in a 32-lead 6 × 6 mm QFN package.
The PE46120 is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator
(SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of
conventional CMOS. Peregrine’s HaRP™ technology enhancements deliver high linearity and excellent
harmonics performance.
