The DSC-R405 is an extremely linear PIN + Amplifier balanced optical receiver suited for a variety of digital and analog applications. The R405 offers a linear response to > 0 dBm optical input, > 0.6Vp-p of linear output voltage, +5dBm of RF output power and a differential conversion gain of 300 V/W. The R405 is available in two bandwidth versions (14 and 20GHz) and two package choices: single-ended K-connector, & differential GPPO RF outputs.
