Notes
1. The typical current measurements noted in CDMA mode are with the following
settings:
a. CDMA-Cellular (800MHz): Band = IS-2000, Cell-Power = -104dBm,
Channel Number 358
b. CDMA-PCS (1900MHz): Band = IS-2000, Cell-Power = -104dBm,
Channel Number 563
Maximum Slot Cycle Index for both 800MHz and 1900MHz modes = 1
2. The inrush current measurements noted here are with respect to the stand alone
CM52 module at room temperature, the results might vary when the CM52 is used
in the Customer Application.
3. Measurements are based on worst case scenario—CM52 with 3W option. Values
for CM52 with no 3W option could be marginally lower.
