A baseband signal duty cycle protection method and protection circuit

Abstract

The invention discloses a baseband signal duty cycle protection method and a protection circuit. The method includes: generating an identification code and baseband signal configuration parameters based on the working state of the circuit where the baseband signal is located; judging whether to read the configuration parameters based on the identification code, such as reading If the configuration parameter is taken, it is judged whether to correct the input baseband signal based on the configuration parameter; if correction is required, the input baseband signal is corrected based on the configuration parameter so that the output baseband signal meets the duty ratio requirement. The invention can significantly reduce the probability of microwave components being burned, and effectively save the design cost of microwave components or their control circuits.

Description

technical field [0001] The invention relates to the technical field of electronic applications, in particular to a baseband signal duty cycle protection method and a protection circuit. Background technique [0002] High-power microwave components generally use dedicated duty cycle protection devices to achieve power protection for microwave components. However, there are currently two problems with dedicated duty cycle protection devices: one is that the structure and package of dedicated duty cycle protection devices are too large, which is not conducive to the miniaturization design of microwave components or their control circuits; the other is that special duty cycle protection devices The duty cycle setting is relatively fixed, and it is not convenient for real-time dynamic adjustment and subsequent design improvement and adjustment after the design is solidified. Contents of the invention [0003] In order to solve the above problems, the present invention provides...
