High Voltage APD Photodetector Bias Supplies
Rugged low-noise bias supplies for quadrant detectors & trackers
In order to achieve the optimum performance from a photodetector, the high voltage bias supply must not induce switching noise into the system. AMI offers a line of High Voltage Power Supplies for photodetector biasing which implement techniques to minimize sharp switching transients that can interfere with sensitive circuits. To ensure low EMI levels, the output is filtered, the transformer is magnetically enclosed, and the module is electrostatically shielded in a metal case to provide industry leading performance.
The 521A series are a cost effective option that is available with variable output voltages up to +/- 800 VDC. The operating temperature range is -40° to +85°C and the internal circuitry is encapsulated to enable operation in harsh environments.
The 523/524 series are available in a compact hermetically sealed metal case with PCB mount pins that are ideal for use in highly reliable applications with limited space requirements. The 523 offers an adjustable output voltage up to +100 VDC and the 524 offers up to +500 VDC.
Please contact AMI to discuss your application or if you have any questions.

Hybrid eyesafe laser rangefinder receiver is designed for laser rangefinding & surveying equipment. Compact construction is ideal for miniature applications. Fast recovery from To overload allows ranging to close objects without compromising long range performance. The incorporation of an InGaAs APD gives very high sensitivity with time programmed gain to minimize false targets. Operation at both 1.06 µm and 1.54 µm is possible over a wide range of pulse widths.
