TRANSMITTER INCLUDING A COMPOSITE AMPLIFIER |
摘要 |
A composite amplifier includes a main power amplifier (10) and an auxiliary power amplifier (12), which are connected to a load (14) over a Doherty output network (16). Filters (26, 28) are provided for pre-filtering the amplifier input signals in such a way that the signals meeting at the output of the main amplifier have essentially the same frequency dependence.
