Codes-switching modulator of microwave electromagnetic oscillations in form of multilayer surface mobius with the p-i-n-diodes

FIELD: radio engineering, communication.

SUBSTANCE: Mobius surface of the multilayer metal-dielectric-metal-p-i-n-diodes-metal-dielectric-metal is used according to the invention in the code-switching modulator of microwave oscillations, and in each section of such surface there is a capacitive component formed by the rectangular dielectric on two opposite sides coated with the metal plates. It is possible to connect or disconnect the additional plates through the p-i-n-diodes, so that the capacity is discretely increased or decreased (herewith the inductance will remain unchanged). The closure in the form of the one-sided Mobius surface of the two metal plates forms one metal plate in the form of the two short-circuited inductor turns.

EFFECT: changing the resonance characteristics of the travelling and standing wave mode by connecting or disconnecting the additional plates to the container in the modulator using the p-i-n-diodes.

SUBSTANCE: microwave modulator includes extended structure on the basis of magnon crystal from ferrite film, microstrip converters for excitation and reception in ferrite film of surface magnetostatic waves, which are arranged on opposite ends of structure, constant magnetic field source, element for control of distribution parameters of magnetostatic waves. Magnon crystal is made on the basis of film from yttrium iron garnet with surface periodic structure in the form of parallel grooves the depth of which is 0.01-0.2 of film and which are arranged perpendicular to axis of extended structure. Element for control of distribution parameters of magnetostatic waves is arranged on the side of grooves and represents metallic shield movable in the direction perpendicular to plane of periodic structure and connected to piezoelectric actuator connected to electric generator of modulating signal.

EFFECT: providing the possibility of controlling the rejection level of microwave signal in frequency band without control direct current flowing along metal film.

FIELD: pulse modulators.

SUBSTANCE: proposed pulse modulator has subtraction stage that generates regulation error signal and depends for its operation on difference between input and feedback signals, and also signal conversion stage that functions to convert regulation error signal into control signal. The latter is multiplied by complex mixed signal at operating frequency ω0 in first multiplication stage. At least one of acting and imaginary parts shifted to signal higher frequency band is then quantized by quantization sage thereby generating actual pulse signal, This signal is then used to produce feedback signal for subtraction stage residing in feedback unit. Such pulse modulator provides for flexible regulation of quantization noise.

EFFECT: ability of shifting suppressed quantization noise toward desired operating frequency.
