ST-1000C SM R 1.0 SMARTRUNK SYSTEMS, INC.

4.3.4.

Automatic Transmit Power

Control

The RF power detector (BAS70)

detects  transmitted  feedback  then
sends  the  readout  to  audio
processor U8. The special firmware
module  compares  the  transmitted

power against the referred level
stored on current channel memory

adjusting the power control level

generated as reference by one DAC
output on the same processor (U8)

then amplified by U3 (MCP6241U)
controlling the gate current on Q1

and Q17.
