23 GHz Linear PhotoReceiver (PR-23-A)

Data Sheet

The Optilab PR-23-A is a linear photo receiver designed for analog applications to 23 GHz.

Product Overview

The Optilab PR-23-A is a linear photo receiver designed for analog applications to 23 GHz. It features high linear TIA gain and dual GPPO RF output. 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 offers two gain control modes: Manual Gain Control (MGC) mode or Automatic Gain Control (AGC) mode. In MGC mode, PR-23-A 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.
