Abstract
Monolithic microwave integrated circuit is a production of the active and
passive components in microwave circuits on a semiconductor substrate, its
operating frequency from 1 GHz above to l00GHz, widely used in a variety
of different technologies and circuit. Monolithic microwave integrated
circuit includes a circuit of a variety of functions.
The phase shifter is a two - port network used to provide the phase
difference between the input and output signals, which can be controlled
by the control signal ( DC bias ) . Digital phase shifters in phased array
radar and digital beam forming system has been widely used, the phase
control signal is added to each unit of the array , making the radiation
beam to scan the space required.
This paper first analyzes the basic principle of a variety of digital phase
shifter circuit topology, and then analyzes the composition of the phase
shifter , passive components and describes the model of the switching
device PIN diode . Agilent's ADS software, is used to design five-digit
Ka-band MMIC phase shifter , and optimizate to achieve better electrical
properties

1.1 MMIC发展概况
单片微波集成电路(Monolithic Microwave Integrated Circuit，简称 MMIC)是
一种把有源和无源器件制作在同一块半导体基片上的微波电路，其工作频率从 1GHz
到 100GHz 以上，在各种不同技术及电路中被广泛应用 [1]
。MMIC 电路包括多种功能电
路，如低噪声放大器(LNA)、混频器、功率放大器、上变频器、调制器、检波器、压
控振荡器、开关、移相器、MMIC 收发前端，甚至整个发射/接受(T/R)组件。由于MMIC
