DESCRIPTION
Packaged proprietary design InGaAs photodiode (PD), that is optimized for high input optical
power and maximum output current linearity. The device is designed to work for RF over fiber
links that require high dynamic range, low noise figure and high RF gain. The internal
components are soldered and laser welded, ensuring maximum reliability and performance
stability with ambient temperature variation. To ensure maximum RF gain the receiver is
packaged with no internal 50 Ohm termination and DC coupled output. The device operates
with external bias T connected to the RF output port.
