ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent damage. Functional operation
is not implied under these conditions. Exposure to absolute ratings for extended periods of
time may adversely affect reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specifications.

Table 4: Electrical Specifications
(TC = +25 °C, fo = 1765 MHz, VCC = 3.4 V, VREF1 = 3.0 V,
VREF2 = 3.0 V, (unless otherwise specified) )
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.
