1.0 Introduction
AMI Semiconductor’s wireless product portfolio includes the AMIS-50050 spread spectrum baseband controller. AMI Semiconductor’s AMIS-5005x products simplify the design of direct sequence spread spectrum radios. They contain all the baseband circuitry needed to implement a radio, thus providing an economical solution to the extensive digital hardware requirements of high performance spread spectrum radios. The AMIS-50050 is a low power device optimal for portable battery powered applications. It utilizes a 3.3V power supply and interfaces to a 3V microprocessor and logic.
