摘要

在雷达和医学成像系统中应用毫米波频率的宽带脉冲调制有相当大的兴趣[1,2]。这些系统的精度和分辨率是由最小脉冲宽度(PW)决定的。此前有报道称，在24/79GHz载波频率下，PWs可降至300ps[1,3]。本文提出了第一个基于集成天线的脉冲发射机的设计，以在硅材料中实现毫米波频率下100ps以下的PWs。发射机产生35到376ps范围内的可变测量功率。为了获得这一性能，人们探索了将PA/天线混合开关与高速数字开关电路相结合的方法。

A 90GHz-carrier 30GHz-bandwidth hybrid switching transmitter with integrated antenna

There is considerable interest in wideband pulse modulation at mm-Wave frequencies for application in radar and medical imaging systems [1,2]. Accuracy and resolution in these respective systems are determined by the minimum pulse width (PW). PWs down to 300ps have previously been reported for 24/79GHz carrier frequencies [1,3]. This paper presents the design of the first pulse-based transmitter with integrated antenna to achieve sub-100ps PWs at mm-Wave frequencies in silicon. The transmitter generates variable measured PWs in the range of 35 to 376ps. To obtain this performance, hybrid PA/antenna switching has been explored in combination with high-speed digital switching circuitry.
