AUTOMATIC TRANSMIT POWER
CONTROL

The RF power detector (U1) detects
transmitted  feedback  and  reverse
power  feedback,  and  then  the
detected signals are send to power
control  stage  (U9)  to  be  compared
with  the  referenced  power  control
coming  from  TX  audio  processor
(U20). The reference power level are
set by the main processor (U37) to
the audio processor (U20) in agree
to the current channel information
stored into the memory.

Power  control  stage  (U9)  also
compares

the

reverse

power

feedback coming from power meter
bridge  (U1)  to  protect  the  power
module  in  case  of  antenna
mismatching.

The  output  of  the  power  control
stage  (U9)  is  fed  direct  to  the  RF
power Amplifier (U3) controlling the
DC bias input of the hybrid module.

Evenly when power level is adjusted
by software on three levels (Hi, Med,
Lo) the power value can be adjusted
to  any  desired  value  between  zero
and  50Watts  by  the  alignment
software.
