AMPD-D High Speed Amplified Microwave InGaAs Fast Photodetector

Introduction of AMPD-D Fast Photodetector The AMPD-D is a fast photodetector hybrid integrated by broadband InGaAs photodiode and low noise amplifier. The response wavelength of InGaAs PIN photodiode is 1000 to 1650nm. The RF gain of a low noise amplifier is 30dB.  AMPD-D can provide the bandwidth of 12GHz and 20GHz. The module operates on +9V supply voltages. It complies with a standard single-mode 9/125μm fiber input. The RF output port is an SMA-compatible connector matched by 50-ohm impedance.  AMPD-D is hermetically sealed and weighs less than 23 grams.  ROHS 2.0 certificated.

Precautions

1. The fiber bending radius is no less than 20 mm to avoid fiber damage.
2. Be sure the fiber coupling facet is clean before connecting it to Opto-circuit.
3. Suitable ESD protection is required in storage, transportation, and use.
