High-Speed, Low-Light Analog APD Receiver Modules LLAM Series

Source: Excelitas Technologies
Excelitas Technologies' newest addition to their high performance sensor portfolio, the LLAM series of avalanche photodiode (APD) modules, features an avalanche photodiode chip, thermoelectric (TE) cooler and preamplifier, all in a hermetically-sealed package. The LLAM series modules are specifically designed for the detection of high-speed, low-light analog signals and allow for measuring longer distances with higher accuracy in LIDAR, range finding, and distributed temperature sensing applications.

Excelitas Technologies' new LLAM series APD modules are offered as standard, commercial off-the-shelf (COTS) products. In addition, Excelitas Technologies offers customized modules tailored from our standard designs; modifications include bandwidth optimization from 1 MHz to 300 MHz, special APDs, and FC-connectorized packaging.

The module, supplied in a single modified 12-lead TO-66 flange package, is easy to install and offers additional heat sinking. The use of a TE cooler ensures lower noise and constant responsivity over a 5°C to 40°C ambient temperature range.

Excelitas Technologies' LLAM series modules are specifically designed for the detection of high-speed, low-light analog signals. The LLAM series use the Silicon C30954EH APD and InGaAs C30645EH and C30662EH APDs, with optimal spectral responses between 830 and 1550 nanometers and very fast rise and fall times at all wavelengths.

Excelitas Technologies' LLAM series of APD are fully RoHS-compliant

"At Excelitas Technologies, we are proud of our heritage as the original architect and leader behind APD technology," said Michael Ersoni, senior vice president and general manager of Excelitas Technologies' global detection business. "The LLAM-1550-R08BH is a direct response to our customers' quest for lower noise, higher speed, and low-light level detection. Excelitas is focused on bringing OEMs continued innovations across our low-light level detection portfolio including APDs, SPCMs, CPMs and SiPMs."
