Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] An embodiment of the present invention provides an amplitude equalizer, which uses a voltage-controllable varactor diode to adjust the resonance point of the amplitude equalizer, so that the flatness index of the amplitude equalizer can be adjusted within a set range.

[0039] see figure 1 , shows a schematic structural diagram of the amplitude equalizer provided by the embodiment of the present invention, the amplitude equalizer provided by the embodim...

Abstract

The invention provides an amplitude equalizer. The amplitude equalizer comprises a resonant point adjustment module and a voltage adjustment module. The resonant point adjustment module comprises a varactor, and the voltage adjustment module is connected with the resonant point adjustment module for adjusting voltages applied to the varactor, such that capacitance of the varactor is changed and resonant points of the amplitude equalizer are further adjusted. The amplitude equalizer provided by the invention can perform adjustment according to requirements of different systems without redesign of the amplitude equalizer for the different systems, and greatly reduces the research and development cost and the research and development time.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an amplitude equalizer. Background technique [0002] With the rapid development of communication electronic systems, the communication bandwidth continues to increase. At present, most of the amplifiers made by device manufacturers are broadband amplifiers. Broadband amplifiers have a common feature, that is, the gain is low when the frequency is high, and the gain is high when the frequency is low. For the transceiver channel of the communication system, in order to realize the power amplification of the transmitted signal and the low-noise amplification of the received signal, multi-stage amplifier cascading is required, which will cause the high-frequency band and low-frequency band after the amplitude-frequency characteristics of all devices in a system are superimposed. The gain may be 10dB worse. In order to achieve a good gain flatness of the channel, an amplitude ...
