1 General Information
1.1 Concept of Design
LAPLACE power amplifiers are air cooled RF broad band amplifiers which are designed for a wide range of
applications, where good linearity and wide bandwidth together with high gain is needed. The solid state
booster stage is of type “Class A/B” (push-pull) which combines very good stability with good
intermodulation behavior.
Special features:
•
automatic amplification control (AVR);
•
pulse response optimised;
•
protection circuit for output stage;
•
remote control input (e.g. door switch);
•
Front panel BNC input connectors
