1. CM-42 Transceiver Module Outline Drawing
1.1. Mechanical
The CM-42 module has no mechanical elements other that the main PCB assembly. All critical
electronic components are shielded using sheet metal lids and LCP frames to prevent
internal/external electromagnetic interference from degrading the module’s performance and to
prevent the module from interfering with other nearby devices. The following figure shows the
outline drawing for the module. The module is plugged into the fixed mating connector and
secured with eight screws to the standoff components.

1.2.1. Electrical Performance
Electrical performance parameters are valid only when the terminating impedance at the
output of the antenna connector exhibits a VSWR of less than 2:1 for all phase angles in
the frequency band of operation. High VSWR loads at the antenna connector adversely
affect current consumption, linearity, and power efficiency of the module and may
prevent operation or cause internal damage.
The RF performance of the CM-42 fully meets the following specifications:
• IS-2000 CDMA Cellular mode – Per EIA/TIA IS-98 specification
• IS-553 AMPS Cellular mode – Per IS-19 specification

1.2.2. Mobile Station Power Class
The CM-42 is able to operate in several modes and different output power levels. Applications may
require output power levels similar to those in a handheld cellular phone or higher levels commonly
required when in rural areas. The table below shows the nominal output power levels of the CM42.

gain with 1.5 dB cable loss)).

Table 1: Power Consumption
1.3.1.1.1 Sleep Mode (Minimum DC Power consumption)
A power down mode is available in which the module is placed in a low power consumption state
under control of the host application. In this mode, the unit consumes approximately 110 uA of
current as measured from the VCC_5V supply input and 4 uA of current as measured from the
VCC_12V supply input. To activate this mode, the WAKE signal on pin 12 of the system
connector pulled to a logic level 1 which puts the module into the low power state. The module
will stay in the low power state until the WAKE signal is driven low by an external open collector
transistor in the application circuitry. Turning the external open collector transistor off will cause
the WAKE signal to float high and turn the module off. The WAKE line is tied to VCC_5V through
a 220kΩ pull-up resistor so the sink current in the external open collector transistor is minimal.
