Optical Data Receiver with Avalanche Photodiode and 1.3Ghz Amplifier

Pacific Silicon Sensor="/crlive/files/Images/15CF9E0A-4AF6-11D6-A789-00D0B7694F32/ad13gto5.jpg" align="left"><%=company%> announces the introduction of an Ultrasensitive Optical Data Receiver, part number PSS-AD500-1.3G-TO5, designed for near IR wavelengths and with a bandwidth of 1.3 Gigahertz (–6db) utilizing a 500µm diameter avalanche silicon photodiode (APD). The spectral response of the receiver is in the 350nm to 1050nm range with a peak response at 750nm. At a bias of 155 volts the gain of the APD is 200. The APD is coupled with a transimpedance amplifier that operates on 3.5 to 5.0 volts and both the APD and the amplifier are contained in a hermetically sealed TO5 housing. The combination provides output of 40mV p-p for a radiant 880nm input of 1 microwatt.

The PSS-AD500-1.3G-TO5 provides a significant cost advantage over receivers operating in the far IR range (i.e., 1300nm and longer).
