Abstract:

An X-band, beam-type parametric amplifier capable of operating in a 20 instantaneous band of frequency is under development. The device is a degenerate type with the pump frequency fixed at 21 Gc. The amplifier is to have an r-f gain of 25 db and a double-channel noise figure of 2 db. Cold test results for the modified bifilar helix coupler and the quadrupole pump circuit are presented. The general construction of the electron gun, coupler, pump, and collector are discussed a detail with special emphasis on bifilar helix support, vacuum envelope seals, and overall tube and beam alignment. Preliminary generation of a magnetic field having an axialfield variation of 0.5 percent are presented. Also discussed is a specially designed collector minimizing secondary electron interference.
