Compact multiaperture couplers for ultra-wideband millimeter-wave (mmWave) operation are presented, employing an artificial magnetic conductor (AMC) for radiation-free performance. Elliptical coupling apertures are used to enable efficient operation across a 50% bandwidth, while fixed elliptical matching patches are employed for any coupling level to achieve matching levels exceeding −19 dB. Minimal phase and amplitude variation are achieved over 15 dB directivity within coupling ranges from 3 to 20 dB. Validation through fabrication and testing of two packaged lines with different aperture configurations confirms practicality and efficiency.

In the above letter, Park and Eom applied a Fourier-transform technique to the analysis of H-plane parallel-plate T-junction. However, the letter has some incomplete relations, and lacking a fundamental theoretical discussion. Moreover, the proposed solution fails to track edge singularities. This comment aims to apply some corrections and demonstrate the deficiency of the proposed solution.

A compact Ka-band differential four-way Wilkinson power divider (WPD) is presented, in which a $lambda $ /4 differential transmission line (DTL) is implemented with multicoupled inductors (MCIs). The inductors allow the DTL to be small using the mutual inductances and their interwinding capacitances effectively. The divider implemented in a 28-nm RF CMOS process occupies a compact area of 0.07 mm2. It shows low insertion losses of less than 1.31 dB at 24–30 GHz and less than 1.86 dB at 24–40 GHz. The measured isolation between the output ports is higher than 17.2 dB at 24–40 GHz.

The synthesis of nonconventional topologies has become the key enabler of next-generation filters. However, the coupling matrix (CM) reconfiguration path of noncanonical forms may become complex and difficult to trace, especially in high-order filters. As a consequence, the synthesis of this kind of networks is usually tackled by means of optimization and numerical interval methods. Although these synthesis methodologies have proven to be effective, for some cases they may take large amounts of time to get to the target topology. This work presents a methodology to extract the reconfiguration path of any target topology once the general transformation matrix is obtained, which is reproducible independently of the transfer function. This enables the option of using the powerful and rapid tool of CM reconfiguration. Moreover, this letter discusses the nonunique solution of a target topology with their reconfiguration path, which is strongly related to the eigenvalues of the network. Two different topologies are used as a vehicle to validate the presented methodology.
非常规拓扑结构的合成已成为下一代滤波器的关键驱动因素。然而，非标准形式的耦合矩阵（CM）重构路径可能会变得复杂且难以追踪，尤其是在高阶滤波器中。因此，这类网络的合成通常采用优化和数值区间法。虽然这些合成方法已被证明是有效的，但在某些情况下，它们可能需要花费大量时间才能达到目标拓扑结构。本研究提出了一种方法，一旦获得通用变换矩阵，就能提取任何目标拓扑结构的重新配置路径，而且这种方法不受传递函数的影响，具有可重复性。这样就可以选择使用 CM 重构这一强大而快速的工具。此外，这封信还讨论了目标拓扑与其重新配置路径的非唯一解，这与网络的特征值密切相关。两种不同的拓扑结构被用作验证所介绍方法的载体。

In this letter, a novel broadband passive intermodulation (PIM) model was developed to evaluate the spectral regrowth around PIM signals. This proposed model adopts the frequency division method to divide the PIM products and introduces the modified Gaussian distribution to fit the probability density function (pdf) of the PIM spectrum. Compared with the power division model, the proposed frequency division model can achieve accurate spectral regrowth estimation in a selected channel. Finally, an example of a coaxial connector was selected and a series of broadband PIM tests were conducted to verify the effectiveness of the model.

This letter introduces a novel input excitation approach designed to enhance output back-off (OBO) efficiency and gain by incorporating both amplitude and phase modulations for an outphasing power amplifier (OPA). For the first time, a comprehensive mixed-mode modulation approach is presented. To validate the proposed method, a prototype OPA operating at 2.6 GHz is designed as the testing benchmark. Experimental results confirm that the power added efficiency (PAE) at 9 dB OBO point reaches 72.56% under the proposed modulation, achieving an 18.76% improvement over the classic modulation. The gain remains relatively stable, ranging from 10.7 to 12.1 dB across a large OBO range.

A dielectric filter using a shared cavity with a quasi-box-like topology is proposed. In the shared cavity, four TE101 mode resonators with a dispersive coupling are cascaded to obtain a quasi-ellipse response. A coupling iris is employed to isolate cross coupling and provide source-load coupling based on the absorption effect of dispersive coupling on cross coupling while not on source-load coupling. This design offers a controllable transmission zero (TZ) which extends the stopband up to $1.85~f_{mathbf {0}}$ with rejection greater than -20 dB. A design example is fabricated and measured. The simulated and the measured results show good consistency for validating the wide out-of-band suppression characteristics of the proposed filter.

This letter presents the new concept and method of feed line resonator (FLR). Unlike the conventional filter feed lines, which serve solely for external coupling, the proposed feed line resonators can not only introduce additional transmission poles within the passband, but also generate transmission zeros at both sides of the passband, thereby significantly augmenting the filter’s performance without enlarging its physical dimensions. A novel and systematic method for constructing multimode resonators, called the connected line resonator (CLR) method has been proposed, two parallel lines are connected to obtain three resonant modes for filter design. The key advantage of this proposed CLR is its ability to exhibit a substantial attenuation slope at the higher band edge. To demonstrate the FLR and CLR method, two wideband filters were designed based on the high-temperature superconducting film, with the center frequency at 7.3 GHz, and the fractional bandwidth of about 59%. The measured results agree well with the simulation ones.

This letter investigates and models the scalability differences in ISV and OSV gallium nitride high electron mobility transistors (GaN HEMTs). This letter provides detailed model parameters for ISV and OSV devices. Based on the extractions, the different scalability rules for ISV and OSV devices are analyzed and modeled. Finally, this letter applies the proposed scaling rules to the Angelov model, showing that the scaled models have excellent accuracy in terms of S-parameter and large-signal behaviors.

This letter presents a D-band frequency doubler integrated with a power amplifier to achieve high output power and efficiency in 45 nm RFSOI. The proposed frequency doubler generates a broadband fully differential output by extracting the second-order harmonic from the shared source and drain nodes of a push-push differential pair and amplifying it through a common gate (CG) stage. The power amplifier exploits a novel device, the ADNFET developed by GlobalFoundries, which exhibits improved breakdown voltage for higher output power and efficiency. The fabricated IC integrates the proposed frequency doubler and power amplifier and reports the measured saturation output power greater than 10 dBm (11.7 dBm at 116 GHz) with a peak drain efficiency higher than 12% (15% at 116 GHz) from 114 to 126 GHz.
