Abstract

A high performance RF Receiver frontend desires a large dynamic range to pick up weak signals from background noise and interference. However, inherent nonlinear distortions of electronic amplifiers and mixers often bottleneck the receiver's dynamic range performance. In this paper, we present a solution to the RF receiver frontend that is based on integrated microwave photonics. It contains a chip-level integrated high dynamic range RF photonic link with an optical-domain frequency down-con-verter. The design and measurements of the integrated circuit are discussed. An approach of extending the IC chip to a fiber-optic fed RF receiver frontend is also presented.
集成微波光子学用于高性能射频接收机前端
一个高性能的射频接收机前端需要一个大的动态范围来从背景噪声和干扰中提取微弱的信号。然而,电子放大器和混频器固有的非线性失真常常成为接收机动态范围性能的瓶颈。本文提出了一种基于集成微波光子学的射频接收机前端解决方案。它包含一个芯片级集成的高动态范围射频光子链路和光域频率下变频器。讨论了集成电路的设计和测量。本文还提出了一种将集成电路芯片扩展到光纤馈电射频接收机前端的方法。
