C30659 Series 900/1060/1550/1550E
Si and InGaAs APD Preamplifier Modules
Excelitas’ C30659-1550E InGasAs APD Preamplifier Modules exhibit enhanced damage threshold
and greater resilience when exposed to higher optical power densities.
Excelitas Technologies’ C30659 Series includes a 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.
The Si APDs used in these devices are the same as used in 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 Excelitas’ regular C30950 Series.
The C30659 is pin-to-pin compatible with the C30950 Series with a negative output.
An emitter follower is used as an output buffer stage. To obtain the wideband
characteristics, the output of these devices should be capacitively- or AC-coupled to
a 50 termination. The module must not be DC-coupled to loads of less than 2,000
Ohms. For field use, it is recommended that a temperature-compensated HV supply
be employed to maintain a constant responsivity over temperature.
Excelitas’ InGaAs C30659-1550E Preamplifier Modules, with 1550 nm peak
response, are designed to exhibit higher damage thresholds, thus providing
greater resilience when exposed to high optical power densities.
Customization of the C30659 Series of APD Preamplifier Modules is available
to meet your specific design challenges; modifications include bandwidth and gain
optimization, use of different APDs, FC-connectorized packaging.
