Product introduction

The KY-BPRM series balanced photoreceiver integrates two matched high linearity analog PIN detector and low noise broadband transimpedance amplifier, with high gain, high sensitivity, DC coupling output and high common-mode rejection ratio(CMRR). This can effectively reduce the common mode noise of the input light and improve the signal to noise ratio of the system. The module is powered by positive 12V, and the input optical interface is optional for optic fiber or space incidence. The electric signal is SMA output, mainly used in nanosecond optical pulse detection, laser radar, optical coherent tomography,fiber optic sensing systems and other fields.
