1. The document discusses load pull matching tuning for various bands (B1, B2, B3, B20, B28A, B28B) of a transmitter. 2. It provides port definitions and topology descriptions for multiple transmitter cases for each band. 3. It also calculates desense from receiver band noise of transmitter leakage for each band to determine the maximum transmitter power before desense occurs.

26. Notice:
1. Insertion loss都跟OCL_linkbudget_Tx_02202017估得差不多
2. 只需考慮online後 power ACLR and current consumption去挑(順序ACLR-->耗電流)
3. B1 B2 B3 B20 B28A B28B Tx跟 Avago Skyworks FAE 一樣
