Optical Coherent Receiver-EWX-6G

Optical Coherent Receiver is composed of a 2×4 90° optical hybrid, four balanced photodetectors and linear trans-impedance amplifiers (TIAs) with differential outputs. Optical 90° hybrid translates the incident signal and LO signal into in-phase (I) and quadrature (Q) phase channels which are converted to electrical signals by pairs of BPDS with integrated TIAs. The operating temperature range is from -40℃ to 70℃. Electrical 3dB bandwidth is more than 6GHz. RF output is SMA or SMPM, which is convenient for system connection. With high integration, the size and weight are greatly reduced compared with traditional discrete components. It is widely used in free space optical communication, RF photonics, LiDAR, test and instrument.
