Note 2: Vcon = 2.85 V is set to obtain Iidle ~
- 75 mA when VCC1, VCC2 = 3.6 V
Note 3: ACPR
a) Pc (1.23 MHz) is average power measured for 1.23 MHz bandwidth with CDMA signal.
b) P (30 kHz) is average power measured for 30 kHz bandwidth with 900 kHz/1.98 MHz offset.
c) ACPR1 (or ACPR2) = P (30 kHz) - Pc (1.23 MHz) dB
Note 4: These electrical characteristics are measured using Toshiba recommended test board.
