The brand new analysis board accelerates growth of 1550 nm infrared techniques, enabling exact efficiency benchmarking and ultra-low noise measurements for LiDAR, optical networks, and rangefinding.
A brand new analysis board designed for next-gen infrared techniques guarantees to simplify and velocity up the event of high-sensitivity 1550 nm photonic functions. Aimed toward engineers engaged on laser rangefinders, optical communication techniques, and LiDAR, the compact platform helps Phlux Know-how’s Aura household of avalanche photodiodes (APDs), which boast as much as 12 occasions higher sensitivity in comparison with conventional InGaAs detectors.
Measuring simply 70 mm x 60 mm, the board integrates a MAX40661 business off-the-shelf (COTS) transimpedance amplifier and helps a spread of key photodiode measurements—darkish present, responsivity, NEP (Noise Equal Energy), IRN (Enter Referred Noise), impulse response, rise/fall occasions, and output swing. These parameters assist designers benchmark efficiency in opposition to legacy or various options in real-world setups. The important thing options are:
- Protected DC-coupled enter
- AC-coupled differential or single-ended outputs
- Customary 50-ohm SMA connectors
- Single +3.3 V DC energy provide
- Preset Vbias for optimum responsivity
- Suitable with 250 MHz oscilloscope for time-domain evaluation
Versatility is in-built. The platform accepts each TO-46/TO-56 hermetically sealed APD packages and Ceramic PLCC6 SMD codecs with quartz home windows—making it straightforward to swap in and take a look at completely different detectors, whether or not Phlux’s personal or third-party gadgets. Past the usual analysis board, the corporate additionally affords an ultra-low noise discrete amplifier design delivering NEP efficiency beneath 30 fW/√Hz. Paired with the Aura 200 µm APD, it helps bandwidths as much as 75 MHz, making it excellent for long-range and defense-grade LiDAR techniques the place precision and low noise are vital.
On the coronary heart of the platform is the corporate’s patented Noiseless InGaAs APD know-how. By including antimony (Sb) to the InGaAs materials, the gadgets obtain excessive inner acquire (as much as 120+), superior temperature stability, and fast large-signal restoration—pushing the boundaries of what’s attainable in low-light IR detection.The board is accessible for order now, offering a quick monitor to analysis and prototyping of infrared sensor functions.
