Abstract:
1. A circuit comprising: at least one first power amplifier; at least one first matching circuit coupled to the at least one first power amplifier; and, at least one first filter coupled to the at least one first matching circuit, at least one second power amplifier; at least one second matching circuit coupled to the at least one second power amplifier; and, at least one second filter coupled to the at least one second matching circuit; wherein a signal received by the at least one first power amplifier is transmitted to the at least one first filter through the at least one first matching circuit and a signal received by the at least one second power amplifier is transmitted to the at least one second filter through the at least one second matching circuit; at least one switch coupled to the at least one first and at least one second filters; and a decoder coupled to provide control signals to the at least one first and at least one second power amplifiers and to said at least one switch.
