Notes/Equations
  1. This subnetwork model is used to measure the RF signal average power. The schematic is shown in the following figure.
    Each firing, one token is consumed.

  2. The average block power is the value measured based on each data block while the average total power is the value measured based on all past blocks.
  3. Power is measured on the load resistance specified by RLoad. The output is watts.
  4. The 3GPP system chip rate is 3.84 Mcps. The BS_Tx_MaxPower.dsn design demonstrates the use of this subnetwork model in the Examples WCDMA3G/WCDMA3G_BS_Tx_prj; this project is discussed in Base Station Transmitter Design Examples.
