AGILTRON AMFPD Low-Noise Optical Detector Amplifier

Product Information

Description
The AMFPD is an amplified, switchable-gain, InGaAs photodetector in an FC/APC Connector with an operating wavelength range of 900 to 1700 nm. Double connector(J2) allows the user to vary the gain in 10 dB steps. A buffered output drives 50 Ohm load impedances up to 5 V. The output signal is readable from the RF SAM connector.

Setup

Input Connector
Refer to Fig 1. Connect the input optic signal with the FC/APC connector.

Power Supply
The power supply is double DC 12V. To connect J1(2.54mm 3 pin connector), see Fig 2.

  • Recommended power supply: Globtek GT-51084-12N12

Output
The output is connected with the RF SAM female adapter. A buffered output drives 50 Ohm load up to 5V. Refer to Fig 3.

Gain (Av) Adjustment
The responsivity of a photodiode can be defined as a ratio of generated photocurrent (IPD) to the incident light power (P) at a given wavelength:

  • R(λ) = IPD / P

Gain (Av) Adjustment:

  • Av = IPD x Rf

Terminal J2 shut connector position compared with Gain:

  • Rf = 100
  • Rf = 1000
  • Rf = 10000
  • Rf = 100000

Mechanical Drawing
Refer to the product datasheet for the mechanical drawing.

Product Usage Instructions

  1. Connect the input optic signal using the FC/APC connector.
  2. Connect the power supply using the J1 connector and recommended power supply Globtek GT-51084-12N12.
  3. Connect the output to the RF SAM female adapter.
  4. Adjust the gain using the J2 connector by selecting the appropriate Rf value based on the desired gain.
  5. Read the output signal from the RF SAM connector.
