摘要
介绍采用混合贴装倒扣二极管技术制造的新型24GHz平衡混频器.并对该混频器进行设计、仿真、加工和测试.它能提供中频100kMz时小于10dB的变频损耗,本振与信号之间优于35dB的隔离度.其结构特点利于大批量、低成本生产,适合汽车电子系统的需求.
Abstract
A mixer employing a planar flip chip GaAs Schottky diode has been designed and tested at 24GHz. Using a planar diode eliminates the disadvantages of mechanical instability and large parasitical parameters associated with conventional whisker contacted diodes. The realized mixer provides conversion loss lower than 10dB and LO -to -RF isolation higher than 35dB. It is specially suitable for applications in automotive electronic system because of its simple structure and low cost.
