Product Technical Specification
Detailed Interface Specifications
3.14. RF Interface
The RF interface of the HL7518 module allows the transmission of RF signals. This interface has a
50Ω nominal impedance.
3.14.1. RF Connection
A 50Ω stripline can be used to connect to standard RF connectors such as SMA, UFL, etc. for
antenna connection.
