ABSTRACT:
A photodetector unit for a photodetector module for optical communication includes a photodetector circuit unit constituted by a ceramic board on which a photodiode for converting input light into an electrical signal and a preamplifier IC connected to the photodiode by bump bonding are mounted, and which has a photodetector circuit connected to the preamplifier IC by bump bonding, and a main amplification circuit unit constituted by a ceramic board on which a main amplification IC is mounted, and which has a main amplification circuit connected to the main amplification IC by bump bonding. The ceramic boards of the photodetector circuit unit and the main amplification circuit unit are mechanically and electrically connected to each other such that a mount surface of the preamplifier IC becomes perpendicular to a mount surface of the main amplification IC.
