broadband amplifier การใช้

• RF circuits are significantly different from broadband amplifier circuits.
• The mixed signals are sent into a broadband amplifier, then sent into the cable system by the trunk line and continuously re-amplified as needed.
• In 1925, from patent sales and publication income, Ardenne substantially improved the broadband amplifier ( resistance-coupled amplifier ), which was fundamental to the development of television and radar.
• Raytheon engineer William C . Brown's work to adapt magnetron principles to create a new broadband amplifier is generally recognized as the first CFA, which he called an "'Amplitron " '.
• During World War II he discovered the work of Rudolf Kompfner in a British radar lab, where he had invented the traveling-wave tube; Pierce worked out the math for this broadband amplifier device, and wrote a book about it, after hiring Kompfner for Bell Labs.
