The 232FHSS modules are part of the family of WiSE (Wireless Serial Engine) modules. A WiSE module combines a state-of-the-art FSK data transceiver and a high-performance protocol controller to create a complete embedded wireless communications link in a small IC-style package. The 250mW RF transceiver is built around the Analog Devices ADF7020 IC, whereas the 25mW version uses the Semtech XE1203F transceiver IC. Both transceivers are designed with the components necessary to facilitate operation in the 902-928MHz US ISM band.
