3 GHz High Gain Avalanche PhotoReceiver Module (APR-3-M)

Data Sheet

Product Overview

The Optilab APR-3-M is a 3 GHz bandwidth receiver module designed for RF over fiber, antenna remoting, and broadband RF over Fiber applications. It features a high gain transimpedance (Zt) value of 20,000Ω. The APR-3-D can accept input power as low as 26 dBm. This compact, cost-effective receiver module can provide users with status monitoring through the use the useful bandwidth of 7GHz can be obtained, and a RS-232 I/O interface. When the APR-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 ultra-wideband RF to fiber conversion applications.
