This is lower than expected due to a slight underestimate of the loading of the prescaler but it can be adapted easily by modifying the VCO’s inductor layout. The maximum TX gain per antenna path is 31dB when the PA operates in ClassA mode with a P1dB of 10.8dBm and a maximum PAE of 33% (see Fig. 13.4.3). Operation at 5dB backoff from P1dB, as required for QAM16 transmission, reduces PAE to 5%. In Class-AB mode, gain and P1dB reduce to 22.5dB and 8dBm, but the PAE at backoff has increased to 7.4%. The 3dB TX RF bandwidth
