20 GHz Photodiode Module


PQW20C-L is a high power, high-speed microwave photodiode module designed for direct optical-to-electrical conversion of RF-modulated optical signals up to the Ku-band. The photodiode provides high responsivity of 0.8 A/W with a 3dB bandwidth of 28 GHz. It enables high RF output power thanks to a linear response up to 13 mW average optical input power.
The optical input is supplied through a 9/125 µm single-mode fiber pigtail. The bias voltage is supplied by DC pins through an internal bias-tee. The RF K-connector output is DC coupled and RF matched to 50 Ω.
