5 RF Specifications
Appropriate antenna type and design should be used with matched antenna parameters according to
specific application. It is required to perform a comprehensive functional test for the RF design before
mass production of terminal products. The entire content of this chapter is provided for illustration only.
Analysis, evaluation and determination are still necessary when designing target products.
