TV-amplifier A3540
A3540 broadband TV-amplifier covers all international VHF and UHF TV-frequencies. It is intended
for use in shipborne CAS-systems and is well
suited for distribution of digitally modulated signals. A separate S-band input is provided for distribution of e.g. satellite signals.
Two separate automatic level control circuits
(ALC) help maintain the output level stable under
the varying conditions often encountered aboard
ships.
A push-pull hybrid amplifier in the final stage
keeps intermodulation to a minimum.
