Avalanche photodiode (APD) module LLAM Series

Product overview
The LLAM-1060-R8BH is a high-speed, low-light Si avalanche photodiode (APD) receiver module for analog signal detection. It integrates a 1060 nm Si APD with a 0.8 mm active diameter, a preamplifier and a thermoelectric (TE) cooler in a hermetically sealed modified 12-lead TO-66 flange package. The module provides a 200 MHz bandwidth and is intended for applications requiring sensitive detection of fast analog optical signals.

Series description
The LLAM Series combines an APD chip, integrated preamplifier and TE cooler inside a hermetic package to ensure stable performance over temperature. The modified 12-lead TO-66 flange simplifies mounting and provides additional heat sinking. The TE cooler maintains lower detector noise and stable responsivity across an ambient range of 5°C to 40°C. Modules are RoHS compliant and supplied ready for integration into optical detection systems.

Integrated components
Includes the Excelitas C30954EH APD.
