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 d B in 0.5 d B 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 peting module solutions. It is offered in a 32-lead 6 × 6 × 0.85 mm QFN package. The PE46120 is manufactured on Peregrine’s Ultra CMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of Ga As with the economy and integration of conventional CMOS. Peregrine’s Ha RP™ technology enhancements deliver high linearity and excellent harmonics...
