The PE53231 is a highly integrated front-end module targeted for wireless infrastructure applications such as TDD macro/micro base stations and MIMO applications. It is designed for use at the front end of a receiver chain for TDD-based systems and is ideally suited to 5G solutions or small cell applications. The dual-channel receiver integrates two independent LNAs with bypass function and a high-power switch. The PE53231 can be utilized across the 3.45 GHz–4.2 GHz frequency range with internal impedance matching networks. This receiver utilizes pSemi’s UltraCMOS® SOI technology which supports input RF power signal up to 20W average power, assuming 9 dB PAR and a very low noise figure, excellent linearity and very low power consumption. Each channel is controlled individually within the selected frequency band, which allows more flexibility in the system design.
