| PROBLEM TO BE SOLVED: To provide a low-frequency amplitude modulator or a low-frequency phase modulator by using a controllable BAW(bulk acoustic wave) resonator, which shifts the resonance frequency according to the applied voltage. SOLUTION: A BAW resonator 102 consisting of a piezoelectric layer and protective layer electrodes, etc., is constructed on a substrate by means of a prescribed material and process. Then the resonator 102 is built into an amplitude modulation circuit 91 as a modulator. When the modulating low-frequency signal, which is produced by an oscillator 96 is filtered by an LPF 98 and an RF choke 100 and applied between the electrodes 102a and 102b of the resonator 102, an electric field is generated on a piezoelectric layer 102c and vibration time-wise varying according to the signals is produced. A prescribed RF carrier signal that is produced by an oscillator 90 is filtered and applied to the resonator 102. The carrier signal is attenuated by the resonance frequency, as well as the impedance caused by the low-frequency signal of the resonator 102. Then the amplitude modulation is carried out. In a phase modulation mode, the oscillation frequency of the oscillator 90 is set almost equal to the parallel resonance frequency of the resonator 102. Then the phase shift is carried out. | ||||||

| PROBLEM TO BE SOLVED: To provide a compact frequency modulation device without need especially of tuning or the like including the signal amplification processing circuit in the poststage by using a surface acoustic wave delay line. SOLUTION: This device is provided with the surface acoustic wave delay line 10 for which an interdigital transducer IDT 2 and the IDT 3 on an input side and an output side are formed with a prescribed distance from each other on the surface of a piezoelectric substrate 1, the pair of electrodes 4 and 5 for impressing modulation voltage signals formed on the propagation path of the surface acoustic waves of the delay line 10 and the back surface side and a feedback circuit 20 for feeding back voltage signals from the output side IDT 3 of the delay line 10 to the input side IDT 2. In this case, to the feedback circuit 20, an amplifier 21 and a surface acoustic wave filter 22 formed on the piezoelectric substrate 1 are inserted. By passing through only a specified frequency band among the frequency bands of the delay line 10 by the surface acoustic wave filter 22, the oscillation frequency of a delay line oscillator composed of the surface acoustic wave delay line 10 and the feedback circuit 20 is strictly selected, the carrier signals of high purity are obtained and circuit constitution is made compact simultaneously. | ||||||

| PURPOSE:To improve the modulation frequency characteristics and relaize a wide band, by setting the reciprocal value of the delay time of propagation of an elastic surface wave filter used for a delay element at a double value or more of the maximum modulation frequency. CONSTITUTION:Action of oscillation is carried out by a positive feedback loop comprising an amplifier 31, a variable phase shifter 32 and a band pass filter 33, and the phase condition is varied by the shifter 32 to control the frequency of oscillation. In this case, the degree of inclination, i.e., the delay time of propagation is decided for the filter 32 so that the phase characteristics of the filter is set at pi radian or a lower change of phase with the frequency axis that is decided by the maximum modulation frequency Fmax. As a result, the delay time of propagation of the filter 33 can be set at 1/2.Fmax or less. | ||||||

| 1524495 Phase modulators MARCONI CO Ltd 31 March 1977 [8 April 1976] 13588/77 Heading H3R In an SAW delay line phase shifter suitable for use in a phased array or commutated array antenna system and providing a single of a plurality of constant amplitude outputs with variable and large phase swings (2# radians), a frequency dependent phase shift is imposed on a variable frequency f 1 or a side-band frequency e.g.f 0 -f 1 ) by passing it through a SAW delay line and this phase shift is transposed on a signal of frequency f 0 by employing modulators M 1 , M 2 to effect appropriate combination and filters BP 1 , BP 2 to filter out unwanted sidebands. The phase of the output signal of frequency f 0 is varied by a variation of the frequency f 1 of oscillator VCO. Effects of the temperature on the circuit operation may be minimized by forming (Fig. 4, not shown) part of the oscillator feed-back phase shift path and the delay line on the same substrate. A plurality of outputs at different phase may be obtained by using different tappings on the delay line. For multi-phased input reception, the multiple inputs (Fig. 3, not shown) are shifted to a side-band frequency by f 1 and the side-bands undergo varying phase shifts before combination and reconversion to the original frequency f 0 . | ||||||
