264-339814 InGaAs APD Preamplifier Module with TEC

About CMC Electronics Inc., Displays and Sensors

• Type: InGaAs
• Light Spectrum: VIS, NIR, SWIR

CMC Electronics’ 264-339814 series uses an InGaAs APD with low ionization ratio of 0.2, with a built-in preamplifier and a thermoelectric cooler (TEC), enabling optimum signal to noise performance.

The APD is coupled to a GaAs FET input transimpedance amplifier in a 12-lead TO-8 package. The amplifier has an overload input protection circuit that sustains high optical power exposure with a very fast recovery time. An integral TEC allows temperature control of the APD, supporting APD module gain and temperature stabilization. The internal temperature can be monitored via an embedded thermal sensor close to the APD. The module is designed for a 100- ohm output load connection (AC or DC coupled, as required by design). Customizations such as bandwidth selection, NEP screening, responsivity optimization and packaging are available, to fit your system design needs.
