C30659-1060-3AH - Si APD Receiver, 3mm, TO-8, 50MHz
The C30659 Series includes a Silicon (Si) or InGaAs Avalanche Photodiode (APD) with a hybrid preamplifier, in the same hermetically-sealed TO-8 package, to allow for ultra-low noise operation. Our C30659-1060-3AH device has a C30956EH Si APD, optimized at 1060 nm, and a 3 mm active diameter.
The C30659 Series features an inverting amplifier design with an emitter follower used as an output buffer stage.
The Si APDs used in these devices are the same as used in the Excelitas’ C30817EH, C30902EH, C30954EH and C30956EH products, while the InGaAs APDs are used in the C30645EH and C30662EH products. These detectors provide very good response between 830 and 1550 nm and very fast rise- and fall-times at all wavelengths. The preamplifier section of the module uses a very low noise GaAs FET front end designed to operate at higher transimpedance than our standard C30950 Series.
