20 GHz High Power Photodiode Module


PQW20B-L is a high power microwave photodiode module designed for direct optical-to-electrical conversion of RF-modulated optical signals up to 20 GHz. The photodiode inside this module is a high power, high linearity Albis photodiode chip, designed to operate in the wavelength region from 1260 to 1620 nm. It offers a typical bandwidth of 22 GHz for photocurrents up to 50 mA, a responsivity of 0.8 A/W and high linearity of up to 50 mA average photocurrent.

The optical input is supplied through a single-mode 9/125 mm 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.
