본 논문에서는 재구성 가능한 새로운 구성을 갖춘 고효율 다중 대역 전력 증폭기(PA)를 제시합니다. 이는 다중 대역 작동에 사용할 수 있는 대역 전환 가능 매칭 네트워크(BS-MN)와 바이어싱 네트워크(BS-BN)로 구성됩니다. 서셉턴스 블록(SB)이 있는 BS-MN은 일부 목표 임피던스에서 SB가 없는 BS-MN보다 더 짧은 전송 라인(TL)이 필요합니다. 본 논문은 SB와 목표 임피던스가 있거나 없는 BS-MN에 필요한 TL 길이의 관계를 이론적으로 도출합니다. 제안된 구성의 장점을 논의하기 위해 목표 임피던스에서 필요한 TL 길이를 수치적으로 평가합니다. 대역 스위칭용 스위치를 채용한 BS-BN은 DC 바이어스 전류가 스위치를 통해 흐르지 않기 때문에 추가적인 DC 전력 소모 없이 증폭 장치에 DC 전력을 공급할 수 있다. 수치 분석을 통해 BS-BN이 여러 대역에서 낮은 손실로 구성될 수 있음이 확인되었습니다. 제안된 구성을 기반으로 1/1.5/1.9/2.5GHz 쿼드 밴드 재구성 가능 PA는 RF 마이크로 전자 기계 시스템 스위치와 분할된 저온 동시 소성 세라믹 기판을 사용하여 설계 및 제작되었습니다. 제작된 1W급 PA는 모든 동작 모드에서 30dBm 이상의 고출력과 40% 이상의 최대 전력 부가 효율을 달성한다.

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.
