1.1. Mechanical
The DM-10 module has no mechanical elements other that the main PCB assembly. All critical
electronic components are shielded using sheet metal cans 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 a typical
mounting configuration of the module with the main motherboard assembly. The module is
plugged into the fixed mating connector and secured with four 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 DM-10 fully meets the following specifications:
• IS-136 TDMA Cellular mode – Per IS-137 specification
• 553 AMPS Cellular mode – Per IS-19 specification
