Abstract

The invention discloses a frequency multiplier. The frequency multiplier comprises a first Lange coupler, a first transmission circuit, a second transmission circuit, a second Lange coupler and a first filter circuit, wherein the first Lange coupler responds to input signals, so as to form a first transmission signal and a second transmission signal which have the same amplitude and phase difference; the first transmission circuit is connected with the first Lange coupler and used for receiving the first transmission signal from the first Lange coupler and conducting frequency doubling amplification and fundamental wave suppression on the first transmission signal; the second transmission circuit is connected with the first Lange coupler and used for receiving the second transmission signal from the first Lange coupler and conducting the frequency doubling amplification and the fundamental wave suppression on the second transmission signal; the second Lange coupler is connected with the first transmission circuit and the second transmission circuit and used for merging signals transmitted by the first transmission circuit and the second transmission circuit, so as to provide output signals with the third harmonic generation; the first filter circuit is connected to the second Lange coupler and used for further suppressing and filtering fundamental waves and outputting relatively pure triple frequency harmonic.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to a frequency multiplier with a millimeter wave balanced structure. Background technique [0002] In the application of millimeter-wave integrated circuits, as the frequency continues to increase, the frequency stability, precision and phase noise performance of the oscillator become worse and worse, and the direct signal generation through the oscillator becomes worse with the increase of the fundamental frequency. It is getting more and more difficult. For a high-performance signal source, a frequency multiplier is a better choice, and frequency multipliers are often components of millimeter-wave (mmWave) datacom, radar, and prototyping systems. In the prior art, a frequency multiplier with a single-tube structure is usually used. However, the harmonic suppression effect of the frequency doubler with a single-tube structure is not good, and the suppression capabi...
