Notes:
(1) Includes the current at pins 1, 4, 5, and 9.
(2) ACPR is specified per IS95 as the ratio of adjacent power in 30 kHz BW to the total in-band power
(1.23 MHz BW).
(3) Includes the current at pins 1 and 9 (Vcc current).
(4) RxBn is measured at 80 MHz above the operating frequency (Fo).
(Measurement setup: RBW = 30 kHz, VBW = 30 kHz).
(5) All phases, time equals to 10 seconds.
