distributing amplifier การใช้

• For a distributed amplifier the input is fed in series into the amplifiers and parallel out of them.
• Simons also designed its successor, the Model 727 Field Strength Meter; the Model 900 and Model 1015 Sweep Frequency Generators, and the Model SCA 213 Distributed Amplifier.
• The pump power required for Raman amplification is higher than that required by the EDFA, with in excess of 500 mW being required to achieve useful levels of gain in a distributed amplifier.
• For the distributed amplifier the capacitance  that is the width  of the single transistor is chosen based on the highest frequency and the width needed for the current is split across all transistors.
• In later oscilloscopes, a type of amplifier using a series of tubes connected at equal distances along transmission lines, known as a distributed amplifier was employed to amplify very high frequency vertical signals before application to the display tube.
• A better design, called a distributed amplifier, used multiple tubes, but their inputs ( control grids ) were connected along a tapped L-C delay line, so the tubes'input capacitances became part of the delay line.
