InGaAs quadrant pin receiver for laser spot tracking and optical communications offered by CMC Electronics

Aug. 5, 2021
Receiver detects wide optical signal levels, operates in harsh environments, has four transimpedance amplifiers, and has a compact hermetic package.

SAINT-LAURENT, Quebec – CMC Electronics Inc. in Saint-Laurent, Quebec, is introducing a 3-millimeter indium gallium arsenide (InGaAs) quadrant pin receiver for laser spot tracking, laser alignment, guidance, free space optical communications, position sensing, and laser range finding.

This receiver detects wide optical signal levels and operates in harsh and varied environments. It also has a large active area with four transimpedance amplifiers (TIAs) in a compact hermetic package.

The pin receiver module includes a standard ambient light rejection circuit, thus eliminating unwanted background light signals. It can detect optical signals at 1064 and 1570 nanometers to support eye-safe applications.

Features such as single or multi-stage automatic gain control (AGC) provide high-dynamic range as well as elective input filtering for low cross-talk are available to enhance detection accuracy.

Customization of this quadrant receiver is available. Different detector size, bandwidth, AGC levels, fast overload recovery, can be offered to fit customers' system design needs.

Additional features can be incorporated without compromising the weight and size of the receiver. For more information contact CMC Electronics online at
