Abstract

The invention discloses a gain-adjustable radio frequency attenuation device based on a split ring resonator, which mainly solves the problems that an existing radio frequency attenuation device is complex in structure, difficult to achieve gain adjustment and high in power consumption. The gain-adjustable radio frequency attenuation device comprises a substrate (1) and a temperature controller (9), wherein an inner split ring (2) and an outer split ring (4) are transferred on the upper surface of the substrate to form a resonator, a VO2 ring (6) is arranged between the two split rings, and the center points of the three rings coincide; and two openings (3 and 5) of the inner split ring and the outer split ring are distributed in a central symmetry mode along a diagonal line of the upper surface of the substrate, a radio frequency input structure (7) and a radio frequency output structure (8) are symmetrically distributed at the two ends of the other diagonal line of the upper surface of the substrate, and the temperature controller is composed of a heating table (91) and a heat sensor (92) which are tightly attached to the lower surface and the upper surface of the substrate and the heating table respectively. According to the gain-adjustable radio frequency attenuation device, radio frequency gain adjustment of a 3.55 GHz frequency point can be realized under the condition that the geometric structure of the antenna is not changed, and the antenna can be used for 5G communication.

Description

Technical field: [0001] The invention belongs to the technical field of electronic devices, in particular to a radio frequency attenuation device with adjustable gain, which can be used in 5G communication systems. Background technique [0002] Attenuators are important electronic components for controlling signal power levels or eliminating interference signals in contemporary communication systems, temperature compensation, transceiver T / R systems, broadband phased array antenna systems, and 5G mobile communication systems. In the RF field, attenuators are mainly used to reduce RF power and improve network impedance matching or amplifier stability. [0003] Traditional RF attenuators are bulky and consume high power, which cannot meet the needs of current consumer electronics for integration and low power consumption. At the same time, the attenuation of the traditional attenuator is related to the structure, and the attenuation will also be determined after the structure...
