A3552 TV-amplifier covers all international UHF 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. An automatic level control circuit (ALC) helps 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.
