20 GHz PhotoReceiver, Differential Out (PR-20-D)

Data Sheet

The Optilab PR-20-D is a high gain receiver with 20 GHz electro-optical bandwidth.

Product Overview

The Optilab PR-20-D is a high gain receiver with 20 GHz electro-optical bandwidth. Hermetically sealed in a 14-pin mini-DIL package, PR-20-D features dual GPPO connector for differential RF output. It contains a PIN-photodiode (PD) and a Trans-Impedence Amplifier (TIA) / limiting amplifier to provide a high conversion gain up to 2000 V/W and differential output voltage swing up to 500 mV peak to peak. PR-20-D also provides a DCA input to adjust eye crossing and a RSSI output as an accurate indicator of the received signal strength. PR-20-D is ideal for digital system operation up to 23 Gbit/s or analog transmission subsystem to RF over Fiber beyond 23 GHz.
