9.4 Module testing recommendations
When testing your integration design:
• Test to your worst case operating environment conditions (temperature and
voltage)
• Test using worst case operation (transmitter on 100% duty cycle, maximum
power)
• Monitor temperature at the location shown below—this should be the hottest
spot on the device (the WCDMA PA).
Figure 9-1: Recommended thermocouple location
Note: Make sure that your system design provides sufficient cooling for the module. The
RF shield temperature should be kept below 90
°C when integrated to prevent damage to
the module’s components.
9.5 Serial link access
Direct access to the UART1 serial link is useful for:
• Testability operations
• Firmware download (for more information on firmware upgrade, see Firmware
upgrade on page 30)
To allow that access, the following serial link access design is recommended:
