KWS7S3 2.4GHz RF Module User Manual

1. Introduction

KWS7S3 is a 2.4GHz ISM band HDR (high data rate) FH (frequency hopping) transceiver.

It provides three types of digital modulation 16QAM/QPSK/BPSK, and on-air data rate support

12Mbps. The proprietary low MAC feature coupled with high-speed multimedia processor

enables a very high quality wireless multimedia application and a great interference immunity

capability.

1 2: Putting the module on the carrier board with socket. 4. SPI Digital Interface All configurations of KWS7S3 are defined by the values of register map. The register map can be accessed via SPI digital interface coupled with external MCU. All configuration values need to be properly set into four types of register maps. The four types of register map are defined as, PMU registers, RF registers, BB registers and MAC registers.
