pSemi has introduced the first monolithic, silicon-on-insulator (SOI) Wi-Fi front-end module (FEM). The PE561221 is ideal for Wi-Fi home gateways, routers and set-top boxes, this high-performance module uses a smart bias circuit to deliver a high linearity signal and excellent long-packet error vector magnitude (EVM) performance. This 2.4 GHz Wi-Fi FEM integrates a low-noise amplifier (LNA), a power amplifier (PA) and two RF switches (SP4T, SP3T). The monolithic die uses a compact 16-pin, 2 x 2 mm LGA package ideal for either stand-alone use or in 4 x 4 MIMO and 8 x 8 MIMO modules.
The 2.4 GHz Wi-Fi FEM is based on pSemi’s UltraCMOS technology platform - a patented, advanced form of SOI. With its outstanding RF and microwave properties, SOI is an ideal substrate for integration. When paired with high-volume CMOS manufacturing - the most widely used semiconductor technology - the result is a reliable, repeatable technology platform that offers superior performance compared to other mixed-signal processes. UltraCMOS technology also enables intelligent integration - the unique design ability to integrate RF, digital and analog components on a single die.
The PE561221 leverages the intelligent integration capabilities of UltraCMOS technology to deliver exceptional performance, low power consumption and high reliability with 2 kV HBM ESD rating. Through advanced analog and digital design techniques, the Wi-Fi FEM delivers excellent long-packet EVM performance with less than 0.1 dB of gain droop while operating across the entire -40°C to 85°C temperature range. At -40 dB EVM (MCS9), the output power is +19 dBm with less than 0.05 dBm droop in power output after a 4 milliseconds packet. The IC delivers best-in-class dynamic error vector magnitude (DEVM) and current consumption without requiring digital pre-distortion (DPD), and it has excellent MCS11 performance for 802.11ax applications.
The PE561221 is the first product in the pSemi Wi-Fi FEM portfolio. pSemi has plans to introduce 5 GHz Wi-Fi FEM solutions as well. Volume-production parts and samples of the PE561221 are available from pSemi. Click here to learn more.
