Abstract

"CIRCUITO DE ASSOCIAçãO DE IMPEDâNCIA, AMPLIFICADOR DE POTêNCIA". Trata-se de um circuito de associação de impedância para um amplificador de potência de múltiplas bandas que possui uma porta de entrada para recepção de sinais de RF de um amplificador, uma primeira via de percurso para comunicação de sinais de RF numa primeira banda de freq³ência para uma primeira porta de saída, e pelo menos uma segunda via de percurso para comunicação de sinais de RF numa segunda banda de freq³ência para uma segunda porta de saída. A primeira via de percurso inclui circuitos de associação de impedância para associação da impedância da primeira porta de saída e da porta de entrada na primeira banda de freq³ência, e a segunda via de percurso inclui circuitos de associação de impedância para associação da impedância na segunda porta de saída e da porta de entrada na segunda banda de freq³ência. A primeira via de percurso contém circuitos que bloqueiam sinais de RF na segunda banda de freq³ência; e a segunda via de percurso contém circuitos que bloqueiam sinais de RF na primeira banda de freq³ência. Um amplificador de potência de múltiplas bandas inclui um amplificador de múltiplas bandas acoplado com um circuito de associação de impedância para um amplificador de potência de múltiplas bandas.
