3.18. RF Interface

The RF interface of the AirPrime HL77xx modules allow the transmission of RF signals. This interface
has a 50Ω nominal impedance.

3.18.1. RF Connection

A 50Ω (with maximum VSWR 1.1:1, and 0.5dB loss) RF track is recommended to be connected to
standard RF connectors such as SMA, UFL, etc. for antenna connection.
Refer to the following table for the pad description of the RF interface.
