Table 35: Wi-Fi/BT and FM Frequency
The reference circuit designs for the Wi-Fi/BT antenna interface and the FM antenna interface are shown
below. A
π-type matching circuit is recommended to be reserved for both interfaces for better RF
performance. The capacitors are not mounted by default and resistors are 0
Ω.
