C24 Module Hardware Description

Antenna Interface

The C24 antenna connector is the RF interface to the CDMA network and GPS system.

The antenna interface is terminated by an MMCX connector type, which is 50

Ω

impedance

matched at the relevant CDMA frequencies.

The antenna or antenna application must be installed properly to achieve best performance.
