Fiber-Optic Receiver, Butterfly Package, InGaAS, 30 GHz, FC/APC

The F-PD-30-A-H-FCA Linear Fiber-Optic Photoreceiver is designed for analog applications. This compact photo receiver contains a surface coupled coplanar waveguide PIN photodiode and a linear transimpedance amplifier within a hermetically sealed 14-pin butterfly package. With an integrated variable gain amplifier (VGA), F-PD-30-A-H-FCA offers two gain control modes: Manual Gain Control (MGC) mode or Automatic Gain Control (AGC) mode. In MGC mode, it provides a linear conversion gain up to 3000 V/W. At a reduced gain setting, the bandwidth of the F-PD-30-A-H-FCA can be increased up to 35 GHz. In AGC mode, the gain is automatically adjusted to deliver a constant differential output voltage up to 1800 mV. The high conversion gain and low input referred noise makes this linear receiver well suitable for high-speed analog applications, as well as digital applications requiring linear response, e.g., QAM-16.
