Fiber-Optic Photodector, PIN PD, InGaAs, 23 GHz, AC Coupled

The front-illuminated mesa-structured PIN design allows a high input power level of up to 40 mW for F-PD-23 and 20 mW for F-PD-30. Typical diodes can handle only up to a few mW of optical power before saturation.

The coplanar waveguide photodiode design optimizes speed and sensitivity for the 1260 nm through 1610 nm
wavelength range, and assures a high bandwidth frequency response necessary for digital and analog applications. 23 GHz and 30 GHz versions are available.

The F-PD series detector designs are optimized for the single mode telecom wavelengths of 1260 nm to 1610 nm, however, the broad 850 nm to 1650 nm can be covered.

While all the other models in the family are DC coupled, the F-PD-23-A is an AC coupled device. Even with a large DC level, A DC block placed between the photodiode and the SMA RF output connector allows only the AC signals to transmit through. The minimum bandwidth is 60 kHz.
