A microwave photonic phase-tunable down converter with LO frequency doubling is proposed. The link can achieve multiple functions including down conversion, LO frequency doubling and phase shift. An integrated dual-channel phase modulator is introduced for two-channel phase shifting. It is the first time that independent and simultaneous phase shift is experimentally demonstrated. This down converter is characterized by function multiplexing, high electrical purity and convenient operation.

具有 LO 倍频功能的双通道相位可调谐下变频器


提出了一种具有LO倍频功能的微波光子相位可调谐下变频器。该链路可以实现包括下变频、LO倍频和相移等多种功能。引入了集成双通道相位调制器以实现双通道相移。这是首次通过实验证明独立且同时的相移。该下变频器具有功能复用、电纯度高、操作方便的特点。
