• Integrated HBT IC preamp
This 80GHz gain bandwidth product APD detector with HBT preamp
is intended to function as an optical receiver for DWDM, SONET, SDH
optical fiber systems operating at 10Gb/s. This detector operates at both
1310 and 1550nm. The nominal 10kΩ integral thermistor allows accurate
monitoring of the APD temperature and facilitates the design of the APD
bias control circuit. It has a typical transimpedance (Zt) value of 1100Ω
The detector preamplifier is DC coupled and has a differential electrical output.
The FRM5N143DS incorporates a high bandwidth InGaAs APD photo diode, a GaAs
HBT IC amplifier in a hermetically sealed butterfly type package. The APD is processed
with modern MOVPE techniques resulting in reliable performance over a wide range of
operating conditions. The lens coupling system and the single mode fiber are assembled
using Nd YAG welding. It has differential output with DC coupling.
