APD Receivers

The performance of an APD in a specific application is often limited by the pre-amplifier, therefore the pre-amplifier needs to be chosen and implemented with great care in order to achieve the best possible signal-to-noise ratio. Our H-series receivers offer the user an APD with matched, integrated pre-amplifier in a compact, hermetic package.

All the receivers listed below are available with silicon* or InGaAs**-APDs and are therefore suitable for the wavelength ranges 400 – 100 nm and 1000 – 1650 nm respectively.

* (SAE-, SAR-, SAT-Series)

** (IAE-Series)

The H0 series includes a Silicon or InGaAs APD with an optimized low noise hybrid preamplifier for the use in laser range finding, LIDAR, medical and analytical applications. Housed in a modified 5 pin TO-46 package they offer bandwidths up to 1 GHz and a single ended output. Higher bandwidth can be achieved by further lowering the feedback resistor values.

The ultra low-noise H1-series is supplied in a 12-pin TO-8 package and features a built-in temperature sensor to allow temperature compensation. The maximum bandwidth is 1 MHz to 30 MHz depending on the version.

The H2/H3/H4/H5 series of receivers is designed for even faster applications, with bandwidths of to 700 MHz offered. These receivers are supplied in a compact TO-46 package.
