Ideal for Wi-Fi Home Gateways, Routers and
Set-top Boxes, the 2.4 GHz FEM Uses a Smart Bias Circuit to Deliver a High Linearity
Signal and Excellent Long-packet Error Vector Magnitude (EVM) Performance
San Diego - August 14, 2018 - pSemi Corporation (formerly
Peregrine Semiconductor), a Murata company focused on semiconductor integration, introduces
the world’s first monolithic, silicon-on-insulator (SOI) Wi-Fi front-end module (FEM)—the
PE561221. 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. The PE561221 combines
the intelligent integration capabilities of pSemi's SOI technology and Murata’s expertise
in Wi-Fi connectivity solutions and advanced packaging. 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.
new IEEE 802.11ax standard is utilizing high-order modulation schemes (1024 QAM) with
demanding EVM requirements," says Colin Hunt, vice president of worldwide sales at pSemi.
"Traditional process technologies struggle to keep up with both performance and integration
requirements, and only SOI can offer the ideal combination of integration and high performance.
This new monolithic Wi-Fi module is a great example of the types of technology and product
advancements pSemi and Murata can accomplish together."
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 uses a smart bias circuit to deliver a high linearity signal and excellent
long-packet EVM performance.
Features, Packaging and Availability
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.
Volume-production parts and samples of the PE561221 are available from pSemi. For

The PE561221 is the first product in the pSemi Wi-Fi FEM portfolio; the product roadmap
includes 5 GHz Wi-Fi FEM solutions.
