Note 1: Guaranteed by design and characterization.
Note 2: T
Note 3: Parameter also applies to demodulator topology.
Note 4: Single-carrier WCDMA with 10.5dB peak-to-average ratio at 0.1% complementary cumulative distribution function,
Note 5: No baseband drive input. Measured with the inputs terminated in 50Ω. At low output levels, the output noise is thermal.
Note 6: The output noise versus P
Note 7: Conversion loss is measured from the single-ended RF input to single-ended combined baseband output.
