Este artigo apresenta um amplificador de potência multibanda (PA) altamente eficiente com uma nova configuração reconfigurável. Consiste em redes correspondentes comutáveis de banda (BS-MNs) e uma rede de polarização (BS-BN) que estão disponíveis para operação multibanda. BS-MNs com bloco de susceptância (SB) requerem uma linha de transmissão (TL) mais curta do que aqueles sem SB em algumas impedâncias alvo. Este artigo deriva teoricamente as relações dos comprimentos de TL necessários para o BS-MN com ou sem o SB e as impedâncias alvo. Os comprimentos de TL necessários nas impedâncias alvo são avaliados numericamente para discutir as vantagens da configuração proposta. O BS-BN que emprega interruptores para comutação de banda pode fornecer energia CC a um dispositivo de amplificação sem dissipação adicional de energia CC porque a corrente de polarização CC não flui através dos interruptores. Análises numéricas confirmam que um BS-BN pode ser configurado com baixa perda em múltiplas bandas. Com base na configuração proposta, um PA reconfigurável de banda quádrupla de 1/1.5/1.9/2.5 GHz é projetado e fabricado empregando interruptores de sistemas microeletromecânicos de RF e substratos cerâmicos co-queimados particionados de baixa temperatura. O PA de classe 1 W fabricado atinge uma alta potência de saída superior a 30 dBm e uma eficiência máxima de potência adicionada de mais de 40% em todos os modos de operação.

Abstract: This paper presents a highly efficient multi-band power amplifier (PA) with a novel reconfigurable configuration. It consists of band-switchable matching networks (BS-MNs) and a biasing network (BS-BN) that are available for multi-band operation. BS-MNs with a susceptance block (SB) require a shorter transmission line (TL) than those without the SB at some target impedances. This paper theoretically derives the relationships of the required TL lengths for the BS-MN with or without the SB and the target impedances. The required TL lengths at the target impedances are evaluated numerically in order to discuss the advantages of the proposed configuration. The BS-BN employing switches for band switching can supply DC power to an amplification device without additional DC power dissipation because the DC bias current does not flow through the switches. Numerical analyses confirm that a BS-BN can be configured with low loss in multiple bands. Based on the proposed configuration, a 1/1.5/1.9/2.5-GHz quad-band reconfigurable PA is designed and fabricated employing RF microelectro mechanical systems switches and partitioned low temperature co-fired ceramics substrates. The fabricated 1 W-class PA achieves a high output power of greater than 30 dBm and a maximum power added efficiency of over 40% in all operating modes.
