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.
