Notes/Equations
- This subnetwork model is the uplink RF source for 3GPP FDD. This subnetwork integrates the 3GPP FDD uplink baseband source with the timed RF modulator.
The output includes the RF uplink signal source, as well as reference baseband signals for EVM and BER measurements.
The schematic for this subnetwork is shown in the following figure.
