The PE561221 is a high-performance monolithic Wi-Fi front-end module (FEM) that combines the intelligent integration capabilities of pSemi’s patented UltraCMOS® technology. On a monolithic die, the PE561221 2.4 GHz Wi-Fi FEM integrates a low-noise amplifier (LNA), a power amplifier (PA) and two RF switches (SP4T, SP3T). This all-silicon die is packaged in a compact 16-pin, 2 × 2 mm LGA to meet the latest 802.11ac Wi-Fi chip-set requirements.
