Title:
進行波増幅器
Document Type and Number:
Japanese Patent JP4290653
Kind Code:
B2
Abstract:
A traveling-wave amplifier includes amplifiers coupled anti-parallel to transmission lines. Phase(s) of the amplifiers provide phase matching, which may additionally or alternately be provided by couplers or spatial offset of the amplifiers and couplers. The traveling-wave amplifier provides compensation for the losses of the transmission lines, amplification of the signals and isolation between input and output by coupling the amplifiers to the transmission lines anti-parallel.
