Abstract
PURPOSE: To secure the specified oscillation terms and thus to improve the oscillation characteristics by providing the variable phase shifter between the delay line and the amplifier forming the elastic surface wave oscillator.
CONSTITUTION: For the elastic surface wave oscillator containing the elastic surface wave delay line 5 and amplifier 4 which amplifies the output of line 5 and then feeds it back to line 5, variable phase shifter 6 is provided between the output of line 5 and the input of amplifier 4. And the value other than the integer value is secured for the value of M when the oscillation and transmission line terms are defined as fOSC = fO/M(n-ϕE/2π) and L = MλO, where fO is the central frequency of the delay line, λO is the wavelength, ϕE is the phase-shift amount of the phase shifter and L is the transmission line length respectively.
