The invention relates to a micro equalizer based on CRLH. The micro equalizer based on CRLH comprises a first gold cladding layer, a medium substrate and a second gold cladding layer which are sequentially laminated from up to down, wherein the first gold cladding layer is provided with a microstrip pattern, an equivalent left capacitor, an equivalent left inductor, an equivalent right capacitor and an equivalent right inductor are formed on the microstrip pattern of the first gold cladding layer, the left capacitor and the right inductor are connected in series, the right capacitor and the left inductor are connected in parallel, and the microstrip pattern of the first gold cladding layer is provided with a resistor used for absorbing microwave energy. Based on the microstrip form, according to the CRLH theory, the equivalent left capacitor, the equivalent left inductor, the equivalent right capacitor and the equivalent right inductor are formed, series and parallel resonance is utilized, resonance on the specific frequency is generated, a stop band of a specific frequency band is realized, the energy is absorbed through fixing the resistor, the equalizer is formed, and propertiesof small volume, simple processing and low cost are realized.
Description
Technical field [0001] The invention relates to an equalizer, in particular to a miniaturized equalizer based on CRLH. Background technique [0002] The traveling wave tube is located at the last stage of the power module and is the main power amplification part of the MPM. The performance of the traveling wave tube directly determines the performance of the module. A major problem with high-power traveling wave tubes currently in use is large gain fluctuations. To achieve a flat power output, an external equalization technology is required. The introduction of the power equalizer successfully solved the problem of excessive fluctuations in the output power of the module. The equalizer is generally placed in the final stage of the solid-state drive module or separately placed between the front-end drive module and the back-end traveling wave tube, which improves the gain fluctuation of the front-end drive amplifier and the back-end traveling wave tube. The miniaturization of eq...
