Abstract

"MéTODO E APARELHO PARA TRANSMISSãO EM BANDA MúLTIPLA". é descrito um método e aparelho para transmitir em bandas de freq³ência de rádio (RF) múltiplas de um único dispositivo. O dispositivo inclui um transmissor (128) para transmitir sinais de comunicação RF. O transmissor é compreendido de um amplificador de potência (200) para amplificar o sinal de comunicação RF quer em uma primeira banda RF ou em uma segunda banda RF. O transmissor tem um transformador complexo (202) para transformar parcialmente a impedância do sinal de comunicação RF em uma primeira banda RF, e transformar completamente a impedância do sinal de comunicação RF para a impedância característica em uma segunda banda RF. O transmissor também inclui uma primeira via (204) para transmitir o sinal de comunicação RF na primeira banda RF e uma segunda via (206) para transmitir o sinal de comunicação RF na segunda banda RF. A primeira via completa a transformação de impedância do sinal de comunicação RF quando o sistema está operando na primeira banda RF e a segunda via opera na impedância característica quando o sistema está operando na segunda banda RF.
