The PRM2144X from Peraso is a mmWave Antenna Module that operates from 57 to 71 GHz. It has a channel bandwidth of 1.08 or 2.16 GHz and supports the IEEE 802.11ad standard with advanced features for long-range, outdoor applications. This module utilizes the Peraso X720 IEEE 802.11ad 60 GHz phased array chipset which includes the PRS4601 B2E baseband processor and a high-power mmWave beamforming transceiver RFIC. The baseband processor provides all MAC and PHY layer functionality necessary for IEEE 802.11ad operation and supports point-to-point or point-to-multipoint capability. It incorporates a 128-element phased array antenna with an azimuth beamwidth of 6°, an elevation beamwidth of 11° and a scan range of ±20°.
The PRM2144X provides fully symmetric throughput up to 3 Gbps (combined) and fully symmetric operation using 2 GHz wide channels and 16-QAM modulation (up to MCS 12). It supports all 6 of the IEEE 802.11ad defined channels and can support links over 2 km range at 1 Gbps data rate. The PRS4601 baseband provides support for up to 32 client devices (stations) in a single network; with 1PPS synchronization and extensions to enable bridging over multiple wireless links. This module supports the latest WPA3 security, 128-bit AES encryption and protected management frames to ensure data protection.
The PRM2144X consumes 11.8 W of power in Tx mode, 4.5 W of power in Rx mode and 1.1 W of power in idle mode. It provides a Tx EIRP of 46 dBm and has an Rx sensitivity of -68 dBm. This module utilizes a 5 Gbps USB 3.2 Gen 1 (SuperSpeed USB 3.0) data interface and Linux WLAN host drivers to simplify system integration. It is available in a module that measures 55 x 55 mm and is ideal for use in point-to-multipoint fixed wireless access networks, point-to-point backhaul and fiber alternative applications.
