20 GHz Linear Balanced Photoreceivers with Optional CDR
|
Description:
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 three package choices: single-ended K-connector, differential GPPO, and a miniature surface mount package with CPW (coplanar waveguide) RF outputs, and utilizes Discovery's high-reliability InGaAs photodiode technology.
