BROAD BAND POWER AMPLIFIER TUBE AND REMOTELY CONTROLLED STEP TUNER(CHANNEL SELECTOR)

摘要

This report covers the design concept, the fabrication, and the acceptance testing of a wide band Klystron tube and. remotely controlled step tuner for channel selection. The equipment was developed for the modification of an existing 20 KW Power Amplifier System which was provided to/the contractor as GFE. The replacement Klystron covers a total frequency range of 2025 to 2120 MHz and is tunable to six (6) each channel with a band width of 22 MHz or greater per channel. A 5MHz overlap is provided between channels. Channels are selected at the control panel located in the front of the Klystron magnet or from one of three (3) remote control stations connected in parallel with the step tuner. Also provided as part of the con¬tract was one (1) each heat exchanger similar to the Trane Company heat exchanger provided with the initial power amplifier under the description UD-40. Included in this final report are the results of acceptance tests conducted at the vendor's plant and of the integrated system tests conducted at Collins Radio Company in Dallas.
