Abstract
We propose a scheme for generating millimeter-wave (MMW) ultra-wideband (UWB) signal that is free from low-frequency components and a residual local oscillator. The system consists of two cascaded polarization modulators and is equivalent to a high-speed microwave photonic switch, which truncates a sinusoidal MMW into short pulses. The polarity switchability of the generated MMW-UWB pulse is also demonstrated.
摘要
我们提出了一种产生无低频分量和残余本振的毫米波（MMW）超宽带（UWB）信号的方案。该系统由两个级联的偏振调制器组成，等效于一个高速微波光子开关，它将正弦 MMW 截断为短脉冲。所产生的 MMW-UWB 脉冲的极性可切换性也得到了证明。
