Part internally matched both on input and output.
Measurements made with device in an asymmetrical Doherty configuration.
Calculated from load pull P3dB measurements.
Exceeds recommended operating conditions. See CW operation data in Maximum Ratings table.
P3dB = Pavg + 7.0 dB where Pavg is the average output power measured using an unclipped W--CDMA single--carrier input signal where
output PAR is compressed to 7.0 dB @ 0.01% probability on CCDF.
