Product Description

The PE565211 is a high-performance, fully integrated 5–7 GHz 802.11ax Wi-Fi front-end module (FEM) that

combines the intelligent integration capabilities of pSemi's patented UltraCMOS® technology. The device

provides all the functionality of a fully-matched bypassable amplifier (LNA), a dual-core power amplifier (PA) and

two RF switches (SP4T, SP3T). The all-silicon die enables an ultra-compact industry-leading 2.5 x 2.5 mm 16-

lead LGA package to minimize valuable PCB layout area, especially for high-density MIMO applications.

The PE565211 maintains maximum linear PA output power from a 3.85V supply for optimal power savings while

low LNA NF enhances receive sensitivity and improves range over a wide variety of conditions. The PE565211

also includes an integrated logarithmic power detector and die-level filtering for sub-harmonic 2.4 GHz rejection

for DBDC operation.

The PE565211 is manufactured on pSemi’s UltraCMOS process, a patented advanced form of silicon-on-

insulator (SOI) technology, offering the performance of GaAs with the economy and integration of conventional

CMOS.
