40 GHz Photodiode Module

Long-wavelength, high-speed microwave photodiode module designed for direct optical-to-electrical conversion of RF-modulated optical signals. The photodetector provides high responsivity of 0.8 A/W with a 3 dB bandwidth of 40 GHz and high linearity of up to 10 mA average photocurrent. The optical input is a 9/125 µm single-mode fiber pigtail with an angled polished, low-reflection FC/APC connector. 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.

The photodiode inside this module is a high performance Albis InGaAs p-i-n photodiode, designed to operate in the wavelength region from 1260 to 1620 nm.
