Description

The 2650A/B provides the proven high performance of our photodiode technology in a very practical, cost-effective package. The 2650-series features high linearity and low capacitance over a 1 GHz bandwidth. These broadband photodiodes are housed in a small, environmentally rugged coaxial package. The 2650A/B broadband photodetector is designed to provide the performance and flexibility needed to meet the expanding applications of two-way commu- nications networks. This photodiode is used today in forward- and return-path applications, including AM- VSB CA TV , QAM 64/256, PON, FTTC, and FTTH receivers.
