We report the RF photonic reception and downconversion of vector modulated RF signals using a millimeter-wave coupled electrooptic phase modulator with in-plane slotted patch antennas based on SEO125 nonlinear polymer. We demonstrate experimental results with QPSK, 8-PSK, 16-QAM, 32-QAM, and 64-QAM millimeter-wave signals centered at 36 GHz. After downconversion to intermediate frequencies between 0.5 GHz and 2 GHz, the vector encoded signals are demodulated using an electrical signal analyzer and found to have measured error vector magnitudes below 8%. Design, simulation, fabrication, and experimental results are presented and discussed.
我们报道了使用基于SEO125非线性聚合物的带有平面开槽贴片天线的毫米波耦合电光相位调制器，对矢量调制射频信号进行射频光子接收和下变频。我们展示了以36GHz为中心的QPSK、8-PSK、16-QAM、32-QAM和64-QAM毫米波信号的实验结果。下变频到0.5GHz至2GHz之间的中频后，使用电信号分析仪对矢量编码信号进行解调，发现测量的误差矢量幅度低于8%。本文展示并讨论了设计、仿真、制造和实验结果。
