23 GHz Linear PhotoReceiver, Hermetically Sealed (PR-23-A-HS)

Data Sheet

Product Overview

The Optilab PR-23-A-HS is a linear photo receiver designed for analog applications to 23 GHz. It features high linear TIA gain and dual GPPO RF output, hermetically sealed for component qualification standards. This compact photo receiver contains a surface coupled coplanar waveguide PIN photodiode and has a linear trans-impedance amplifier within a 14-pin butterfly package. With an integrated variable gain amplifier (VGA), PR-23-A-HS offers two gain control modes: Manual Gain Control (MGC) mode or Automatic Gain Control (AGC) mode. In MGC mode, PR-23-A-HS provides a linear conversion gain up to 1500 V/W. In AGC mode, the gain is automatically adjusted to deliver a constant differential output voltage up to 1200 mV. The high conversion gain and low input referred noise makes this linear receiver well suitable for high speed analog applications.
