Country of Origin: United States. Country of Publication: United States Document Type: CONFERENCE PAPER Most documents available from AIAA Technical Library Journal Announcement: IAA8419 A novel method called 'Dynamic Velocity Taper to linearize the Pout versus Pin transfer characteristic that does not require any extraneous circuitry or tuning, has large bandwidth capabilities (10 percent) and offers also an increase in the intrinsic traveling wave tube (TWT) efficiency by 1 to 2 dB is described. In addition, the method permits the TWT to be operated at or near the synchronous voltage (b plus or minus o) which produces a flat small and large signal gain responses and low AM to PM conversion. The physics of the method and experimental verification are given. The implementation should have a significant impact on TWT performance and increase the channel capacity of communication satellites. Previously announced in STAR as N84-21803 (R.J.F.)

Document Type: JOURNAL ARTICLE Most documents available from AIAA Technical Library Journal Announcement: IAA8418 The paper is concerned with the synthesis of an eddy- current device on the basis of a specified relationship between the output signal and the parameter being measured. The problem of synthesis is reduced to that of determining the characteristics of the probe signal of the eddy- current transducer, with constraints on the power of the signal. A synthesis equation is obtained, and the synthesis of a device with a linear output characteristic is illustrated by an example. (V.L.)
