Preamplifier

The preamplifier should increase the SiPM's weak pulse amplitude by ca. 20dB and must be located as close as possible to the SiPM. Therefore, a plug-on PCB for the SiPM board with the same form factor was designed, which shall be as versatile as possible in order to adapt for different read-out concepts with following properties:
- supply of the SiPM bias voltage through the preamp including bias filter
- AC-coupling of the preamp input
- based on low-noise MMIC BGA614
- mounting option for one or two MMIC stages
