8 Reference Approval
8.1 Reference Equipment for Type Approval
The Gemalto M2M reference setup submitted to type approve ALS3-US R4 is shown in Figure
16. The module (i.e., the evaluation module) is connected to the DSB75 by means of a flex ca-
ble and a special DSB75 adapter. The GSM/UMTS/LTE test equipment is connected via edge
mount SMA connectors soldered to the module’s antenna pads.
For ESD tests and evaluation purposes, it is also possible connect the module to the GSM/
UMTS/LTE test equipment through an SMA-to-Hirose-U.FL antenna cable and the SMA anten-
na connectors of the DSB75 adapter.
A further option is to mount the evaluation module directly onto the DSB75 adapter’s 80-pin
board-to-board connector and to connect the test equipment as shown below.
