WXG45226Q Series 1GHz Balanced Photodetection Receiver Module

Product Description：The WXG45226Q is a high-speed, high-sensitivity balanced-detector photoreceiver module that utilizes a monolithically integrated InGaAs balanced detector mixed with a low-noise transimpedance amplifier for a wide range of digital signal applications. Automatic detuning, gain, and bandwidth control provide stable bandwidth and output swing. The automatic gain control has a shutdown feature that provides a minimum gain of 400V/W after shutdown.
