2 Integrating the CM52 Module

2.1 Overview

The CM52 is a dual band, dual mode CDMA transceiver module. It operates in the 800 MHz band for CDMA and AMPS and in the 1900 MHz band for CDMA. It is designed for consumer and OEM industrial voice and data applications.

The CM52 module is intended for mounting into an application developer’s chassis to provide wireless communication capability for the product. The target chassis could be in a wide variety of forms such as a residential electric meter, a point of sale terminal, an alarm panel, or an automobile console. All initial configuration, mode control, and operational commands are issued to the module over an RS-232 serial port using a flexible AT command format. The module circuitry has been designed to meet the environmental requirements of a large range of commercial and industrial users.

2.2 Mechanical Description

7(42)

The CM52 has no mechanical elements other than the main PCB assembly. All critical electronic components are shielded using six cans to prevent internal andexternal electromagnetic interference from degrading the module’s performance and to prevent the module from interfering with other nearby devices. The module is plugged into the fixed mating connector and secured with four screws.

The antenna interface is provided via a board mounted RF connector at the opposite end of the board from the system connector. See Section 2.8 for more information on antenna connector options.

The module has no keypad, display, microphone, speaker, or battery. The following figures show a mechanical drawing and physical dimensions of the module.

Note! All the measurements are in millimeters.

2.2.2 Heat-Sink Requirements

The application is required to provide a heat-sink for the 3W AMPS capabilities of the CM52.

The application should be designed to provide a heat sink with a thermal resistance of

4.0

C/W.

For applications that disable the 3W mode (Class I) and only operate in 0.6W mode (Class III) a heat-sink is not required.

2.2.3 Mounting Holes

Mounting holes and tabs are provided for proper mechanical support of the CM52 module in the customer’s application. OEM application must provide sufficient mechanical retention using the mounting holes and/or tabs or some other means. The system connector and RF connector connections should not be used as a means of mechanical support. Also, please note that the mounting holes may not substitute for the actual grounding pins provided via the system connector.

2.4 Power Supply

The CM52 requires a dual DC power supply implementation in the application. VCC_MAIN provides power to the entire radio while VCC_AUX provides power for the 3-Watt functionality and biasing for the RF switches. VCC_AUX must be present if the 3W option is provided even if it is not used VCC_AUX is not required.

The following table summarizes the power supply requirements from the application.
