Variable-gain photoreceivers based on the DHPCA amplifiers to 200 MHz
The OE-300 photoreceiver consists of a premium quality photodiode followed by a high-end, variable gain transimpedance amplifier. The low noise performance (NEP) is outstanding and sets a benchmark for wideband photoreceivers particularly in the high and mid-range gain settings. The relatively large sized detectors make optical alignment easy and also ensure a very high coupling efficiency when using the Si models together with the optionally available fibre optic adapters PRA-FC/SMA.
The switchable gain from 10^2 to 10^8 V/A (decade increments) allows precise and reliable measurements within a very wide dynamic range from nanowatts up to 10 milliwatts optical power.
Many additional features like switchable low-pass filters, offset adjustment, switchable AC/DC coupling and the capability of manual and opto-isolated remote control by a PC make the OE-300 the most versatile wideband photoreceiver in its class.
