Document Type and Number:
Japanese Patent JPH01501974
Kind Code:
A
Abstract:
A travelling wave modulator in which the phase velocity of a first wave is modulated by a second travelling wave. Means are provided to alter the polarity of the second wave in accordance with a pseudorandom code. Barker codes and Golay codes are particularly suitable for improving the bandwidth-to-voltage ratio of the modulator over a comparable conventional modulator.
