ABSTRACT:
A high frequency delay circuit operable to output a high frequency signal delayed for a desired delay time. The high frequency delay circuit includes: a variable delay circuit operable to receive a reference signal of which a frequency is lower than the high frequency signal, and to output a delay reference signal delayed from the reference signal for the desired delay time in advance; and a multiplier operable to generate the high frequency signal, of which a frequency is a frequency of the delay reference signal multiplied by a predetermined value, and to output the generated high frequency signal at timing according to a phase of the delay reference signal.
