MAST BAND AMPLIFIER
AMB 800 Series
Supply voltage 24 ± 10% Vdc
Power consumption 93
mA (Recommended FA 802)
Operating temperature range –20...60 ºC
Professional mast band amplifiers, immune to all signals
from other services which share the radioelectric
spectrum, such as mobile phones, wireless transmissions,
terrestrial communications….
APPLICATION
Suitable for individual systems or small installations, with high sensiti-
vity and output power (114 dBµV), the AMB 800 is a heavy-duty
amplifier, ideal for future applications according to new Digital
Terrestrial TV (DTT) requirements. It is prepared to process both ana-
logue and digital signals during the migration towards DTT.
CHARACTERISTICS
■
Very low noise figure and independent from gain regulation
■
Test point at -30 dB that allows level control without interrupting
remote power and function.
■
The mechanical solution guarantees an exceptional immunity
against noise invasion, a critical aspect for DTT reception.
■
3 Notch filters can be adjusted over the whole UHF band, or even in
their extremes to achieve an additional rejection to unwanted signals.
■
F connectors.
