This paper presents the design of a high peak efficiency dual-band power amplifier (PA) and how it is adopted as basic cell to implement a high average efficiency Doherty PA (DPA), achieving a dual-band/multi-mode and efficient transmitter concurrently operating at 1.8GHz and 2.4 GHz. From the dual-band PA, an average PAE of 25% has been experimentally obtained, when exited with concurrent 10MHz LTE and WiMAX signals. When using this PA as a basis for a dual band Doherty PA, the average PAE is improved (by 9 percentage units) to 34%. An adjacent channel leakage ratio (ACLR) lower than -46.5 dBc and -46.0 dBc has been fulfilled from PA and DPA, respectively, using a standard digital linearization technique.
