摘要:

设计了一个毫米波频段的宽带功率均衡器与固态功率驱动模块。通过对用于驱动模块的功率均衡器进行改进，提出了一种新型的微带阶梯阻抗谐振线的功率均衡器结构，这种结构频带宽，驻波好，结构紧凑。为了验证其性能，加工实物并进行测试，测试结果表明，均衡器在32 GHz~40 GHz宽带频段，其最小插入损耗小于3.3 dB，回波损耗优于13 dB，均衡量9 dB。固态功率驱动模块采用2级放大器，且均衡器后置，布局合理。测试结果表明，在32 GHz~40 GHz，功率均衡精确度优于2 dB，输出功率更为准确，实现了固态驱动模块的小型化设计。

Abstract:

A broadband power equalizer with a Solid State power driving Amplifier(SSA) module is designed. Through improving power equalizer used in SSA, a power equalizer structure of novel microstrip Stepped Impedance Resonance(SIR) lines is depicted, with wide frequency band, good standing wave and compact structure. In order to verify its performance, an equalizer is fabricated and tested. The measured results show that in 32 GHz-40 GHz, the minimum insertion loss is below 3.3 dB, return loss better than 13 dB, the value of equalization is 9 dB. SSA module adopts two-stage amplifier and an equalizer is put behind. The test results show that in 32 GHz-40 GHz, the accuracy of power equalization is better than 2 dB, and the output power is relatively accurate, which has realized the compact design of the SSA.
