| 摘 要： | Q波段(33~50GHz)比Ka波段(26.5~40GHz)频率更高,对这一波段国内研究较少。该文设计了一种Q波段宽带四倍频放大组件,该组件包含两级二倍频器、两级之间的带通滤波器和一级毫米波功率放大器,最后通过微带到波导过渡输出。设计宽带带通滤波器的目的是为了抑制基波和三次谐波。测试结果表明,在33~50GHz的输出频率范围内,输出功率大于10.5dB,谐波抑制大于31.6dBc。该倍频放大组件具有输出频带宽、体积小、输出功率高以及谐波抑制度高的特点。

| Abstract: | A Q-Band frequency quadrupler-amplifier module is designed to operate from 33 GHz to 50 GHz. This module consists of two stages frequency doublers, a bandpass filter between two frequency doublers and a millimeter wave power amplifier with a microstrip of waveguide transition. The wide bandwidth bandpass filter is designed to suppress the fundamental and third harmonic signals. In the range of 33 GHz to 50 GHz output frequencies, the measured output power is more than 10.5 dB and the third harmonic signal r... |
