Electrical Characteristics – Band 2 (1700MHz to 2800MHz)

See the F4482 Typical Application Circuit. Unless stated otherwise, specifications apply when operated with VCC = +3.3V, TEP = +25°C,

fRF = 2100MHz, STBY_A = STBY_B = STBY_C = STBY_D = HIGH, ZS = 100Ω differential, ZL = 50Ω single-ended, maximum gain setting,

and output power = 0dBm/tone. EVKit trace and connector losses are de-embedded.
