Avalanche photodiode (APD) module LLAM-1550E-R08BH

Product overview The LLAM-1550E-R08BH is a high-speed, low-light analog InGaAs avalanche photodiode (APD) receiver with a 0.08 mm (80 µm) active diameter. The module integrates a thermoelectric (TE) cooler and preamplifier in a hermetically sealed modified 12-lead TO-66 flange package for simplified mounting and enhanced heat sinking.

Series description The LLAM Series combines an APD chip, TE cooler and preamplifier in a RoHS-compliant hermetic package. The TE cooler reduces noise and maintains stable responsivity across an ambient range of 5°C to 40°C. LLAM-1060E and LLAM-1550E variants are designed with higher damage thresholds to withstand elevated optical power densities. The LLAM-1550E-R08BH includes the Excelitas C30645EH APD.

Applications

• Laser range finding
