6.2.2
Antenna
The choice of the antenna sub-system (type, performance, cable length and thermal resistance, etc.) and its
integration in the application is a major issue. These elements could affect the performance of the GSM
features such as sensitivity and transmitted power.
It is recommended to shield the application.
For applications including an antenna, poor shielding could dramatically affect the sensitivity of the terminal.
Therefore, the antenna should be isolated to the maximum extent possible from the digital circuitry
(application digital circuits and Integra Wireless CPU
®
interface). If not, the power transmitted through the
antenna could affect the application.
Product used within 20 cm from the head or body is required to undergo SAR testing. Because of the
industrial application of the Integra M2106+, the Wireless CPU
®
has not been qualified for SAR. Customer
should make sure that the antenna placed is having a minimum distance of 20cm from human body.
