1.
Intermediate SAW filter technology for very sharp out of band rejection
to amplify only specific operators’ signals and reject al l the
others.

3.
To maintain safe and specific output signal levels and give alarms on
self-oscillation, the repeater has built-in AGC and ALC circuits, which
can automatically control the gain of the repeater depending upon the
strength of input signals.

4.
Auto shut off design available for both uplink and downlink to avoid
serious interference to network effectively when the repeater is in
deep self-oscillation or very strong input power.
