Abstract EN
This paper proposes a new broadband Doherty power amplifier topology with extended back-off range.
A shunted λ/4 short line or λ/2 open line working as compensating reactance is introduced to the conventional load modulation network, which greatly improves its bandwidth.
Underlying bandwidth extension mechanism of the proposed configuration is comprehensively analyzed.
A three-device Doherty power amplifier is implemented for demonstration based on Cree’s 10 W HEMTs.
Measurements show that at least 41% drain efficiency is maintained from 2.0 GHz to 2.6 GHz at 8 dB back-off range.
In the same operating band, saturation power is larger than 43.6 dBm and drain efficiency is higher than 53%.
