Title:
帯域幅が重なっていないカスケーディング・マルチパス干渉ジョセフソン方向性増幅器を使用した周波数多重化マイクロ波信号の増幅
Document Type and Number:
Japanese Patent JP7185984
Kind Code:
B2
Abstract:
A cascading microwave directional amplifier (cascade) includes a set of Josephson devices, each Josephson device in the set having a corresponding operating bandwidth of microwave frequencies, wherein different operating bandwidths have different corresponding center frequencies. A series coupling is formed between first Josephson device from the set and an nth Josephson device from the set, such that the first Josephson device amplifies a signal of a first frequency from a frequency multiplexed microwave signal (multiplexed signal) and propagate without amplification a signal of an nth frequency, and the nth Josephson device to amplify the signal of the nth frequency and propagate without amplification the signal of the first frequency from the multiplexed signal in the first signal flow direction through the series.
