10 / 25 page PEB 2023 PEF 2023 Overview Semiconductor Group 10 08.97 In figure 3 the S-transformers are replaced by the PEB/F 3023 which is called S-Feeder. When using the S-Feeder a capacitive coupling between S-receive-path and the S- Transceiver is necessary. For the S-transmit-path the S-Feeder need an extra 2.4V transmitter supply voltage. Because of the DC-voltage-drop on the S-Feeder (about 2V and 4V) the input voltages V RPM and VNPM must be increased (to about 42V and 44V).
