30 GHz Linear PhotoReceiver, Hermetically Sealed (PR-30-A)

Data Sheet

Product Overview

The Optilab PR-30-A is a linear photo receiver designed for analog applications. This compact photo recevier 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), PR-30-A offers two gain control modes: Manual Gain Control (MGC) mode or Automatic Gain Control (AGC) mode. In MGC mode, PR-30-A provides a linear conversion gain up to 2000 V/W. At a reduced gain setting, the bandwidth of PR-30-A 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.
