a. VDD_RF collectively refers to the VDDIF, VDDLNA, VDDPX, VDDLNA, VDDRF RF power supplies.
b. Overall performance defined using integrated regulation.
c. VDDTF for Class 2 must be connected to VREG (main LDO output). VDDTF for Class 1 must be connected to VREGHV (HV LDO output) or
an external voltage source. Refer to the Cypress compatibility guide for configuration details. VDDTF requires a capacitor to ground. The value
of the capacitor must be tuned to ensure optimal RF RX sensitivity. Typical 10 pF for BGA packages and 6.2 pF for wafer package. The value
may depend on board layout.
d. Can be 3.3V if the output power is limited to 9 dBm.
