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