TWT Amplifiers

As a single power amplification block, construction of a TWT amplifier is fairly straight forward and is comprised of a high voltage power supply (5 to 20 KV), the TWT, and sundry protection and control circuitry. Depending on the particular application, additional filtering or protection, linearization circuitry, and a pre-amplification block can be part of the amplifier. This last component can often reduce the gain needed from the TWT and increase overall amplifier performance as shown in Figures A and B.
