3 GHz PhotoReceiver, Module (PR-3-M)

Data Sheet

Product Overview

The Optilab PR-3-M is a 3 GHz photodiode module designed for RF over Fiber, antenna remoting, and other RF transmission applications over optical fiber. The PR-3-M utilizes a linear PIN photodiode and low distortion TIA (Transimpedance Amplifier), providing optical to RF conversion beyond 3 GHz. This compact, cost-effective receiver module can provide users with status monitoring via a USB 2.0 port.  When the PR-3-M RF over fiber receiver module is linked with the LT series of RF over fiber transmitter modules, the combination provides an excellent solution for wideband RF to fiber conversion applications.
