6. Range of operating power levels and description of means for
variation of operating power
Dynamic range of output power is from –56dBm to +24.5dBm with
±0.3dB variation in CDMA mode.
A temperature-compensated TX AGC (Automatic Gain Control) amplifier with 85dB gain range is
included in the RFT3100. The transmit output power level is directly controlled by varying the gain of
this TX AGC amplifier. A DC input voltage from the MSM5500 linearly controls the gain of the TX
AGC amplifier.
The 84 dB dynamic range is 39 dB when the voltage 2.8V and -45 dB in 0.1V. The 81 dB dynamic
range (0.3V ~ 2.4V) gain is used in this CDMA Engine.
