Murata subsidiary PSemi has introduced its smallest PA-LNA-SW IoT front-end module (FEM).

Designed to Thread and Matter protocols, the PE562212 ( is a compact multi-protocol 2.4GHz FEM that enables various connectivity options for IoT devices.

With a 14-lead 1.8 by 1.8 by 0.7mm LGA package (MSL3), the IoT FEM is designed for space-constrained applications, delivering flexibility and value to IoT device makers. It enables connectivity across Thread, Zigbee, Bluetooth BDR/EDR, BLE and low-medium throughput wifi (MCS7) as well as 2.4GHz proprietary applications.

It can be used to connect smart speakers, lighting, thermostats and in-home appliances to IoT hubs, as well as range extenders, wireless audio, wearables, sensors, asset tracking, industrial devices and more to ensure link robustness.

“The introduction of PE562212 – PSemi’s first IoT FEM offering – leverages years of innovation and expertise in semiconductor integration and advanced connectivity, packaging the best technology and design architecture into a highly flexible solution for the IoT market,” said Vikas Choudhary, PSemi vice president. “We understand the challenges our customers and IoT device developers around the world face when it comes to space, power consumption and link budget. We are very proud to now offer one of the industry’s smallest IoT FEMs that addresses these challenges head-on for the widest array of IoT applications and devices.”

The IoT FEM is designed with efficiency and linearity in mind as it enables higher data rate applications such as wifi, striking the balance of adequate linear power with that of power efficiency. Powered by PSemi’s proprietary UltraCMOS technology, it leverages capabilities and integration for PCB-limited IoT applications with up to +21dBm output power and digital Tx gain control of 1dB steps with 15dB range. It also delivers Rx capability of 1.5dB NF typical and low IL bypass path of 0.9dB, typical with a GPIO control interface.

The compact design provides PCB space savings and easier board routing as no external SMD components, including control lines, supply lines and RF, are required. It also offers ESD and ruggedness for all intended applications and environmental conditions inherent to the IoT space.

Samples and EVKs are available directly through PSemi, and are expected to be commercially available by August 2024.

PSemi (, formerly Peregrine Semiconductor, designs and develops semiconductor integration, providing capabilities with RF, analogue and mixed signal properties. A wholly-owned subsidiary of Murata (, PSemi is headquartered in San Diego, California, with offices spanning North America, Europe and Asia.
