Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a novel adjustable amplitude equalizer. Background technique [0002] In microwave radio frequency circuits, various broadband microwave devices or modules, such as transmitting and receiving modules, power amplifiers, and millimeter wave power modules, have different degrees of amplitude and phase unevenness. and standing waves, the output waveform will be greatly affected within the entire bandwidth. The amplitude equalizer plays an important role in the transmitting and receiving ends of the radar or various new power components, and can be used to improve the amplitude-frequency characteristics and phase-frequency characteristics of the transmission channel.

Problems solved by technology

[0003] Traditional equalizers are constructed using waveguides or coaxial cables, which are suitable for high-power and high-frequency applications, but they are heavy and bulky, which is not conducive to system integration

Moreover, in the broadband receiving system, the flatness characteristic of the amplitude is also closely related to the dynamic design requirements. Currently, the commonly used amplitude equalizers are all fixed equalizers, which do not have dynamic adjustable characteristics.
