摘　　要：介绍了一款高灵敏度W波段功率检波器芯片的设计及其封装测试结果。该检波器电路采用标准0.1μm Ga As p HEMT工艺设计加工制造完成。封装测试结果显示,当射频输入信号功率为-15d Bm时,检波电路在90~95GHz频率范围内的电压灵敏度大于6000m V/m W。该电路具有很好的宽带特性,可以工作在86~100GHz频率范围内,几乎覆盖了W波段的所有常用频率。此外,该检波器电路芯片结构紧凑,面积仅为2×1mm2,适合高密度的射频前端集成。This paper describes the design and packaged measurement results of a W-band high sensitivity power detector. The proposed detector is developed in a standard 0. 1μm Ga As p HEMT technology. The measured results of packaged module indicate that when the input power of RF signal is- 15 d Bm,the voltage sensitivity is better than 6000 m V / m W from90 GHz to 95 GHz. The module achieves a good wide-band performance,and the span of the operation frequency covers from86 GH to 100 GHz which are extensively used in common W band applications. In addition,this chip has a compact structure which occupies 2 × 1mm^2,making it an ideal candidate for high density RF front-end integration.
