
All internal debugging points inside DTV-UDWG series products are controlled
via microcomputers, after being equipped with GPRS module, the equipments support
the remote debugging. Equipment operating information, fault information could be
remotely-monitored via internet or mobile SMS in real time.

The power amplifier use new generation LDMOS tube, it has the characteristics
of high linearity, high efficiency, and more stable performance.

The equipments currently have the largest range (40dB, maximum 50dB) super
large range AGC control circuit to ensure the stable output power.

DTV-UDWG series products have high-precise ALC compensation function; the
equipment can maintain the stable operation even if external environment changes
sharply.

DTV-UDWG series products use unique original noise power compensation
program to avoid environmental noise on the signal AGC power in small-signal input
circumstance.

DTV-UDWG series products use algorithm with combination of digital and
analog to achieve the output power adjustable in a continuous wide range.

Models below 50 watts can provide the interfaces for external battery backup
power and photovoltaic battery.

Protection against self-excitation: when self-excitation occurs, the repeater will be
self-protect to avoid the damage to high-power amplifier.

DTV-UDWG original input power too-small protection. The repeater gain may
reach the maximum when main transmitting station or fiber-optical link is shut down
for maintenance, if in this status, the main transmitting station or fiber-optical link
operate normally, this will cause large instantaneous power to damage the power
amplifier. DTV-UDWG series products combined the power too-small protection and
nS level shutdown circuit to effectively solve the impact of this effect.

The products are equipped with output power too-large protection and output
reflection too-large protection. User can set the corresponding protection points via the
control panel or remote control.

Super-fast impact protection for Pre-amplifier input overload power. Special rapid
sampling and circuit shutdown can realize cut-off the link between pre-amplifier and
power signal chain in nS level time period.

Power Protection, once the power value deviate from the user settings range, the
system will stop working.

Temperature protection. Users can set the temperature to turn on or turn off the
