摘要

在本文中，我们提出了一种使用低温共烧陶瓷（LTCC）衬底的具有相位变化补偿的小型多尔蒂组合器。基于输入和输出端口之间的关系，使用S参数的相位计算，导出了所提出的多尔蒂组合器的设计理论。在确定了频带边缘频率和相位平衡的目标程度后，设计了所提出的电路。使用微带线和LTCC衬底对所提出的电路进行了验证。所实现的结构以LTCC为衬底，在50W连续波的高功率测试下运行，测试结果还表明，幅度和相位平衡分别在0.2dB和±1°范围内变化。高功率测试表明，所实现的结构适用于高功率多尔蒂放大器或组合器。

A Wideband Doherty Combiner with Phase Variation Compensation Using LTCC Applicable for High Power Transmission

In this paper, we propose a small-sized Doherty combiner with phase variation compensation using low temperature co-fired ceramic (LTCC) substrate. The proposed design theory for the Doherty combiner is derived using the phase calculation of the S-parameter based on the relation between the input and output ports. The proposed circuit is designed after determining the band edge frequency and the targeted degree of the phase balance. The proposed circuit is verified using the microstrip line and the LTCC substrate. The implemented structure, using LTCC as the substrate, is operated under a high-power test of continuous wave 50 W, the results of which also show that the amplitude and phase balance have variations within 0.2 dB and ±1°, respectively. The high-power test shows that the implemented structure is applicable for high power Doherty amplifiers or combiners.
