Antenna Interfaces¶
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.
The xPico 600 module utilizes a dual antenna design with antenna diversity, offering two RF coaxial connectors for enhanced signal reception.
RF Coaxial Connector¶
