微波光子频率转换是许多光无线系统应用中必不可少的关键功能。光子混频器因其宽带潜力、RF和LO端口之间的高隔离度以及抗电磁干扰的优势而备受关注。介绍了宽带微波光子下变频器的新方法，包括可以实现高转换效率的载波抑制技术，以及可以实现高无杂散动态范围的新型线性化结构。
Microwave photonic frequency conversion is a key function that is essential in many optical-wireless system applications. Photonic mixers are attractive because of the wide bandwidth potential, the high isolation between the RF and the LO ports, and the advantage of electromagnetic interference immunity. Recent new methods in wideband microwave photonic downconverters, including carrier suppression techniques that can achieve high conversion efficiency, and new linearized structures that can achieve a high spurious free dynamic range, are presented.
