2.2.2 Power Monitoring- Smart-ALC
Next, the output RF signal is amplified by a power amplifier and combined by a
duplexer before output.
The power amplifier includes power-monitoring circuits with Automatic Level
Control (ALC). The ALC prevents excessive output power while maintaining
the power amplifier linearity.
The Repeater also includes Dekolink's Smart-ALC algorithm for gain control.
This algorithm adjusts the gain of the Repeater paths in case of insufficient
isolation. This feature prevents oscillation while maintaining gain utilization in
the linear range operation.
To reset the Repeater to its highest gain value, it is sufficient to simply turn the
Repeater power off then on.
2.2.3 SAW Switcher
The SAW Switcher enables you to select one out of three frequency bands in
order to adapt the Repeater to the site bandwidth allocation. The selection is
software enabled (see Chapter 6).
2.2.4 Control and Monitoring
The Mini-Repeater operation is controlled by a microprocessor. The processor
monitors the Repeater function and controls the alarm LEDs located on the
Mini Repeater front panel.
2.2.5 Protection
The Mini-Repeater also includes protection against high V.S.W.R. and difficult
operation conditions. An auto recovery mechanism returns the unit to normal
operation, after power or other failures.
