Excelitas C30659-1550-R2AH InGaAs APD Receiver
PART/ C30659-1550-R2AH

C30659-1550-R2AH - InGaAs APD Receiver, 200um, 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 C30659-1550-R2AH device has a C30662EH InGaAs APD, optimized at 1550 nm.

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.
