The Large Hadron Collider will highly increase the luminosity of the accelerator in the course of the HL-LHC project. The CMS experiment, as one of the four major experiments at the LHC, must consequently receive an upgrade, to be able to record data in the high-luminosity era. Almost all subsystems of the detector must be adapted to the demanding conditions in this phase. This work is related to the planned upgrades for the CMS tracker detector. In particular, a completely new detector must be developed, since the current detector would no longer work efficiently, due to radiation damage, and since the requirements for the detector cannot be met with the current technology, due to the higher luminosity. With an active area of 200 m2 silicon sensors, the detector will be able to detect every 25 ns on average 6000 tracks of charged particles with energies above 300 MeV at 200 hard particle collisions. In addition, the tracker detector must provide real-time information about the transverse momentum of the particles to the L1-trigger system and simultaneously function at an increased trigger rate of 750 kHz. Therefore two dedicated types of modules were developed, which combine data reduction and pT -discrimination. One of these pT -modules is the PS module. This work includes the characterization and qualification of the protypes of macro-pixel sensors for the PS module, as well as the first prototype modules. In the course of this thesis, the function of the intelli- gent readout chip is validated. In addition, a new inverted module concept is investigated, which compensates for certain disadvantages of current hybrid- pixel detectors and represents an alternative to the standard module design. The work includes electrical measurements on the sensors, measurements of the detector response with a pulsed infrared laser, as well as with a 5.6 GeV electron beam. Based on the analysis of the results obtained, a recommenda- tion for a future sensor design is given and the perspectives of the inverted concept are explored.
