    摘要： PURPOSE:To obtain an optional phase regulating range by exercising phase control over the signal obtained by dividing an input signal and then multiplying said signal. CONSTITUTION:The input signal is supplied to a terminal 130 and then divided into two parts, for example, by a frequency divider 131. These divided signals are supplied to a phase regulator 132. This regulator 132 consists of a capacitor 121, an inductance 122 and a resistance 123 and can continuously regulate the phase between 180 deg. and 0 deg.. Thus the regulator 132 controls the phase of the 2- divided signals. These regulated signals are multiplied by a frequency multiplier 133 and reset to the original frequency. As a result, the phase regulation range is doubled. Thus it is possible to regulate the phase continuously between 360 deg. and 0 deg..

    摘要： PURPOSE:To obtain a flat frequency characteristic over a broad band by applying a desired phase shift with a single frequency signal and obtaining a mixed output between the single frequency signal phase-shifted in this way and an input signal so as to phase-shift the input signal. CONSTITUTION:The input signal at an input terminal 1 is given to one input of the 1st mixer 6a. A local oscillator 7 is a signal source generating a single frequency signal and the output single frequency is branched into two by a distributor 8. One output signal from the distributor 8 is given to the other input of the 1st mixer 6a, the output of the mixer 6a passes through the 1st filter 10 and is given to one input of the 2nd mixer 6b. The other output signal of the distributor 8 is given to the other input of the 2nd mixer 6b via a narrow band- phase shift circuit 9. The output of the mixer 6b passes through the 2nd filter 11 and is led to the output terminal.

    摘要： PURPOSE:To obtain a variable phase shift control circuit with wide control range and good linearity by providing an up-converter and a down-converter to a signal system, giving a delay time difference to a local signal system of both and controlling variably its local frequency. CONSTITUTION:An output of a voltage controlled variable frequency oscillator 12 generating a local signal is inputted to the 1st frequency converting mixer 1a acting like the up-converter and the 2nd frequency converting mixer 1b acting like the down-converter connected in cascade to a signal system to be phase-shifted via delay lines 9, 10 having different delay time, then the amount of change in the phase is represented by the product between the frequency displacement of the logcal signal and the delay time difference of the two delay lines. Then, the frequency displacement of the local signal is decreased in selecting the latter larger, allowing to improve the linearity and to obtain a wide control range.
