Abstract

The invention relates to a frequency mixing and harmonic wave amplifying efficient ultra-wideband frequency multiplier which comprises a harmonic wave generator which receives fundamental frequency signals, adjusts the working area of the harmonic wave generator by using external input adjusting voltage according to the frequency band requirement of a frequency source, and generates maximum secondharmonic wave, third harmonic wave and fourth harmonic wave respectively; The first to fourth filters are simultaneously connected to the output end of the harmonic generator; Wherein the first radiofrequency switch and the first power amplifier are sequentially connected; A first mixer; A second radio frequency switch; The third radio frequency switch and the second power amplifier are sequentially connected; The fourth radio frequency switch and the second mixer are sequentially connected; Wherein the fifth radio frequency switch and the third power amplifier are sequentially connected. According to the invention, the active device working in the nonlinear region is utilized to generate harmonic waves, and the plurality of radio frequency switches are adopted to amplify or mix each harmonic wave, and then the co-frequency signals are synthesized, so that the efficient broadband signal output is realized.

Description

technical field [0001] The invention relates to a millimeter-wave frequency multiplier, in particular to a high-efficiency ultra-wideband frequency multiplier for mixing and amplifying harmonics. Background technique [0002] In the millimeter-wave radar system, due to the poor stability of the high-frequency millimeter-wave oscillation source, low output power, and high cost, most high-frequency millimeter-wave signal sources use the method of multiplying the frequency of the low-frequency signal source to the required frequency. In this way, a highly stable millimeter wave source can be obtained. [0003] Existing broadband frequency multipliers are generally realized by injection locking, but this method has large frequency conversion loss and low output power; and for the method of directly using active devices to generate high-order harmonics nonlinearly, although the frequency conversion gain can be improved, However, it is difficult to realize a wider frequency band ...
