Peraso Technologies Inc. announced the immediate availability of the PRM2141 IEEE802.11ad/ay module. The device is fully tested to an over-the-air antenna input/output specification, thus relieving OEMs from the complexities of ensuring the integrity of the mmWave RF performance. In terms of performance, the phased array antenna is optimized for both as standalone device and for use with a parabolic reflector.

Using a 40 cm dish antenna, the module has demonstrated links up to 25 kms, as evidenced by the production deployment of Tier 1 OEMs in the wireless ISP market. In a standalone configuration, the modules support a range of more than 500 m. Additionally, the module supports beamforming and beam steering, thus allowing operators the ability to slightly adjust the direction of the beam to ensure optimal performance at such long distances.

"The PRM2141 is the culmination of over a decade of experience in mmWave communications," said Ron Glibbery, CEO of Peraso. "This not only includes our experience in mmWave semiconductor devices, but also our custom phased array antenna technology, extensive real-time software, complex PCB implementation and over-the air test procedures. Globally, no other vendor in the market can provide this level of aggregate skill when it comes to mmWave technology."

The PRM2141 can be used in a variety of applications. Some examples include PtP and PtMP links for fixed wireless access networks, private mmWave networks, 5G base station backhaul and V2X communications.
