Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] MEMS devices used in the field of radio frequency and microwave have the advantages of fast execution speed, low loss and high quality factor. The most mature MEMS device used in the field of radio frequency and microwave is a switch, which is different from traditional semiconductor switching devices such as field effect transistors or PIN diodes. In contrast, MEMS has extremely low series resistance and low execution power consumption, therefore, the loss is very low, and the standing wave characteristics are good, so it has a wide application prospect in microwave circuits.

Abstract

The invention is suitable for the technical field of microwaves, and provides an electronic corrector, which is characterized by comprising a control circuit module and an electronic standard module connected with the control circuit module. The electronic corrector replaces a field-effect tube switch element with an MEMS (micro-electromechanical system) switch element to realize the hardware basis needed by electronic correcting, and the good wave property of the MEMS switch element is utilized to ensure the mutual independence of impedance standards, thus realizing by using less impedance states, reducing circuit complexity and improving calibration efficiency and correcting precision.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to an electronic calibration part and a calibration system thereof.
