CIRCUIT TO EXCITE SURFACE ACOUSTIC WAVES AND GENERATOR OF OSCILLATIONS ON ITS BASIS Russian patent published in 2013 - IPC H03B5/32 

FIELD: electricity.

SUBSTANCE: circuit of resonator (X1) excitation on surface waves, besides, the resonator comprises a static capacitance (Co), and the circuit of excitation is designed to supply voltage (Vx) to the specified resonator, comprises a reactive facility (L3), designed for resonation jointly with the static capacitance (Co) of the resonator on a previously determined frequency (Fo) of initial period of excitation of the resonator at the specified voltage, besides, the excitation circuit comprises a passive facility (R3), designed for establishment of oscillations at the specified predetermined frequency (Fo). The generator of oscillations comprises a resonator on surface waves and the excitation circuit for any of the above claims, specified in the formula.

EFFECT: provision of a resonator excitation circuit on surface waves, which makes it possible to start oscillations very quickly, within about a hundred of nanoseconds.
