PE46140 Monolithic Phase & Amplitude Controller (MPAC)–Doherty

The UltraCMOS® PE46140 covers a frequency range of 3.4 to 3.8 GHz and is ideal for optimizing gallium nitride (GaN)-based Doherty power amplifiers. 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. Each MPAC–Doherty product eliminates the need for discrete components and integrates a 90-degree RF splitter, 5-bit digital phase shifters, a 4-bit digital step attenuator and a digital serial peripheral (SPI) interface on a single monolithic die. The controller covers a phase range of 87.2 degrees in 2.8-degree steps and an attenuation range of 7.5 dB in 0.5 dB steps. View product details.
