The GR0136 from Browan Communications is a Random Phase Multiple Access (RPMA) Module for low-power applications. It operates in the unlicensed 2402 to 2482 MHz and can improve low-power WAN integration if it is embedded within sensor designs. The module delivers a transmit power of 21.5 dBm and has a receive sensitivity of -142 dBm. It uses the DSSS-DBPSK modulation technique and offers AES 128 level encryption. The GR0136 is available in a SiP module that measures 20.50 x 18.00 x 2.35 mm with a proprietary SPI interface and requires a DC supply of 3.3 V. It integrates an Airoha AL2236 IC as its RF transceiver and is ideal for application in 2.4 GHz RPMA networks.
