DC Power Requirements
A DIVISION OF TRIMBLE
30 Hardware Overview
Note
Maximum power may have to be reduced to meet regulatory limits, which
specify the combined effect of the module, antenna, cable and enclosure
shielding of the integrated product.
As shown in the chart, the current draw when the RF output level is set to +27 dBm
reaches the limit of 1A when the DC input voltage is below 3.7 V. Below the 3.7 VDC input
level, the RF level will no longer reach 27 dBm, although no error message will be
returned. The input Voltage should be maintained above 3.7 Volts if the RF output power
setting is above +25 dBm. 3.5 V is adequate for an RF output power level of +26 dBm,
and 3.3 V is adequate for an RF output power level of +25 dBm and below. The chart
