Abstract

A millimeterwave bandpass MMIC amplifier, which integrates both features of gain amplifier and bandpass filter, is presented. A synthesis method for such amplifier is developed from the image-parameter filter theory. By employing the proposed bandpass amplifier in a receiver, the bulky of chip filter may not be required. An experimental chip fabricated by 0.1 /spl mu/m PHEMT shows 14.2dB gain from 20 to 40 GHz and 60-dB attenuation below 7 GHz and above 60 GHz. This confirms the proposed method and shows the feasibility of the function integration of gain amplifier with bandpass filter in the millimeterwave range.

20 ~ 40ghz带通MMIC放大器的设计

介绍了一种集增益放大器和带通滤波器功能于一体的毫米波带通MMIC放大器。从图像参数滤波理论出发，提出了这种放大器的合成方法。通过在接收机中采用所提出的带通放大器，可能不需要庞大的芯片滤波器。0.1 /spl mu/m PHEMT制备的实验芯片在20 ~ 40 GHz范围内的增益为14.2dB，在7 GHz以下和60 GHz以上的衰减为60 db。这证实了所提出的方法，并表明增益放大器与带通滤波器在毫米波范围内功能集成的可行性。
