A single-layer substrate-integrated waveguide (SIW) filtering power divider (FPD) with fully differential operation at 28 and 39 GHz is proposed in this letter. This FPD consists of three SIW cavities where the differential and common modes of each cavity were properly designed to form three-pole dual passbands, facilitate deployment of isolation resistors, and introduce transmission zeros while attaining high in-band common-mode rejection. To improve the output return loss and isolation in dual bands, a novel and simple approach to find the proper location of isolation resistors is presented. At operating frequencies, the measured differential-mode input or output return loss, minimum insertion loss, isolation, and common-mode suppression are >14.1 dB,< (3 + 2.2) dB, >14.9 dB, and >30.3 dB, respectively. The amplitude and phase imbalances between outputs are < 0.48 dB and <4.2°, respectively.

用于 5G 毫米波应用的单层双频平衡基板集成波导滤波功率分配器
这封信中提出了一种在 28 GHz 和 39 GHz 下具有全差分操作的单层基板集成波导 (SIW) 滤波功率分配器 (FPD)。该 FPD 由三个 SIW 腔组成,其中每个腔的差模和共模都经过适当设计,以形成三极双通带,便于部署隔离电阻器,并在实现高带内共模抑制的同时引入传输零点。为了改善双频段中的输出回波损耗和隔离度,提出了一种新颖且简单的方法来找到隔离电阻器的正确位置。在工作频率下,测得的差模输入或输出回波损耗、最小插入损耗、隔离度和共模抑制分别 >14.1 dB、< (3 + 2.2) dB、>14.9 dB 和 >30.3 dB。
