* @brief Device handler for the EIVE Payload PCDU
* @details
* Documentation:
* https://egit.irs.uni-stuttgart.de/eive/eive_dokumente/src/branch/master/400_Raumsegment/412_PayloaPCDUDocumentation/release/EIVE-D-421-001_PLPCDU_Documentation.pdf
*
* Important components:
* - SSR - Solid State Relay: Decouples voltages from battery
* - DRO - Dielectric Resonsant Oscillator: Generates modulation signal
* - X8: Frequency X8 Multiplicator
* - TX: Transmitter/Sender module. Modulates data onto carrier signal
* - MPA - Medium Power Amplifier
* - HPA - High Power Amplifier
