In WCDMA mode, the voltage levels should be:
• 0.4...0.8 V @ Start level 0 dBm
• 0.8...1.3 V @ Start level 10 dBm
• 3.0...4.2 V @ Start level 24 dBm
In GSM mode, the voltage levels should be:
• 0.1...0.5 V @ GSM 900 & Tx Power Level 19
• 0.5...1.1 V @ GSM 900 & Tx Power Level 12
• 3.5...4.3 V @ GSM 900 & Tx Power Level 5
Note: The VPA signal is continuously on when WCDMA TX is activated, but has a pulsed nature in
GSM TX mode (the signal is on only when a GSM TX burst is transmitted).
Note: The VPA signal is not tested by ST_CDSP_RF_SUPPLY_TEST.
