Smart-ALC maintains the Uplink/Downlink gain balance for system transparency. In addition, Smart-
ALC prevents oscillations that may occur due to insufficient isolation while maintaining the gain in a
linear range operation by adjusting the repeater paths’ gain accordingly.
IMOP (Isolation Measurement and Oscillation Prevention) algorithm effectively reduces oscillation
problems.
The repeater’s power amplifier includes power-monitoring circuits with Automatic Level Control (ALC)
that prevents excessive output power while maintaining the power amplifier linearity.
1.6 DMCU - Optional
The DMCU (DIGImini Control Unit) provides complete remote control and monitoring capabilities over
WCDMA/GPRS, including Remote control via SMS.
