孙晓玮, 罗晋生, 周宗闽, et al. Study of Experiment and Design Method for An NRC MMIC Active Voltage-Controlled Filter[J]. Acta Electronica Sinica, 1997, (2).DOI:
This paper presents a kind of the microwave monolithic active filter circuit with GaAs MESFET negative resistance property
and gives a GaAs MESFET varactor construction considering the MMIC procedure-compatibility.Therefore
the active filter has the voltage-controlled function. The design method of monolithic circuit and the CAD results are also given. Finally
the MMIC active filter with chip size of 0.9 × 1.8mm2 is fabricated.The experiment results show that the design method presented is correct and effective.
