HV Detector Bias Supplies

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.

HV APD Bias Supply

 

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.

 

Hermetic HV APD Bias Supply

 

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.

Model 758B.1

Based on the field proven performance of AMI’s 758 Series Laser Rangefinder Receivers, the Model 758B.1 extends the capabilities even further with outstanding double-pulse discrimination. This allows a weak target to be seen through a close, partly obscuring strong target. Multiple Target Resolution is 12 meters typical over 6 orders of magnitude with the second pulse 10dB down.
