Product Overview
The LR-12-A-M is a 12 GHz bandwidth amplified PIN photodiode receiver module designed for RF over fiber, antenna remoting, and broadband RF signals transmission applications using single mode optical fiber.
The LR-12-A-M utilizes a wide bandwidth, low distortion PIN photodiode plus a high-gain linear Trans-Impedance Amplifier (TIA) that provides optical to RF conversion to the frequency range beyond 12 GHz. The LR-12-A-M is a highly linear O/E converter that can be used for every type of analog and digital signal. This compact receiver module can provide users with status monitoring through an RS-232 I/O interface. When the LR-12-A-M RF over fiber receiver module is linked with the LT-12-M lightwave transmitter module, the combination provides and excellent choice for ultra-wideband RF to fiber conversion applications.
