Note 5: Recommended functional range, not production tested. Operation outside this range is possible, but with degraded perfor-
Note 6: All limits include external component losses of components, PCB, and connectors.
Note 7: It is advisable not to operate the I and Q inputs continuously above 2.5V
Note 8: Guaranteed by design and characterization.
Note 9: Single-carrier WCDMA peak-to-average ratio of 10.5dB for 0.1% complementary cumulative distribution function.
Note 10: No baseband drive input. Measured with the baseband inputs terminated in 50Ω to GND. At low-output power levels, the
Note 11: It is advisable not to operate the RF input continuously above +17dBm.
