This paper presents a new coupling matrix solution for a tunable diplexer. By introducing redundant couplings to each channel filter, the interference of the two channels can be greatly mitigated. For the first time, a combline tunable diplexer with cross couplings is demonstrated and verified.

This paper proposes an electronically reconfigurable C-band doublet topology based on a dual-mode coaxial substrate integrated waveguide (SIW) resonator with source-load coupling. Varactor diodes in a back-to-back configuration have been used to tune the filter response in terms of center frequency, bandwidth (BW) and return loss (RL) level. The proposed approach presents a high design flexibility in a very compact size, allowing us to prove both tunable BW and constant absolute BW over a tuning range of about 15% at C-band. As a validation example, a single dual-mode coaxial SIW resonator with 10 varactor diodes is used to implement a 2-pole tunable bandpass filter (BPF) with two transmission zeros (TZs) that has been designed, fabricated and tested. The filter has a fractional BW (FBW) range and insertion loss (IL) better than 100% and 5 dB, respectively, over the entire tuning range.

This paper presents a novel approach to monolithically implement RF phase change material (PCM) germanium telluride (GeTe) T-type switch for millimeter-wave switch matrix applications. The miniature T-type switch demonstrates three states of operation including one cross-over state and two turn-states. A six-layer micro-fabrication process is developed to fabricate the T-type switch. PCM RF series switches are used to route the signal through various RF sections including 90-degree bends and a cross-over junction. The measured results for the proposed T-type switches demonstrate excellent RF performance of less than 0.6 dB insertion loss, better than 20 dB return loss and higher than 20 dB isolation in all states from DC to 67 GHz. To the best of our knowledge, this is the first implementation of PCM based T-type switch ever reported.

This paper performs a comprehensive nonlinear modeling of a Bulk Acoustic Wave (BAW) duplexer operating at the band 7 of the LTE wireless communication standard. The modeling starts by an accurate characterization of the resonators forming the filters by performing measurements of the second harmonic (H2). The modeling of individual resonators has then been used to predict second order nonlinear manifestations occurring in a real duplexer. These are H2, second order intermodulation products (IMD2), for the case where a jamming signal is set to low frequencies (IMD2-Low) and when the jamming signal is set to high frequencies (IMD2-High). Predicted results are then validated with real measurements.

Large scale phased antenna array is considered as one of the key techniques in 5G to enabling the ultra-high-speed data communication. However, the large number of phase shifters in conventional phased array architecture significantly increases the cost and system complexity, which brings it challenges in commercial use. In this article, we propose an innovative phase shifting architecture by mixing two travelling waves rather than using phase shifters. The phases of the antenna elements can be by simply changed by tuning the frequencies of the input waves, while the frequency of radiated signal is kept as constant. A 1 by 8 linear array based on the proposed technique is fabricated and tested. The new structure provides a low-cost solution for large scale array application in 5G.

Two high-gain, broadband power amplifier MMICs are reported. The first result is a 140-GHz 0.25-W PA. It utilizes 5-gain stages and 4-way power combining. S21 gain is 29.4-dB. It demonstrates over 0.21-W Pout across 110-150 GHz. 0.25-W Pout at 140-GHz requires 4-dBm Pin – the associated gain is 16-dB with 7.0% PAE. The 140-GHz OP1dB 1-dB gain compression is 171-mW with 4.9% PAE. The 3-dB S21 bandwidth (BW) is between 112-148 GHz. This result improves state-of-the-art by 65% at 140-GHz for peak SSPA power. The second PA result is a 55-135 GHz 115-135 mW PA. It utilizes 4-gain stages and 2-way power combining. Its operation fully covers WR15 (50-75 GHz) to WR08 (90-140 GHz) bands. S21 gain is 27.3-dB. The S21 fractional BW at 1-dB and 3-dB gain roll-off are 63% and 81%. Large-signal BW associated with high power and gain between 55-135 GHz is 84%. Pout variation over this span at 3-dBm Pin is only 11.2% (±13-mW). This result improves state-of-the-art for mm-wave PA’s where simultaneously high Pout, fractional BW, gain, and gain flatness are required.

One of the challenges for building a quantum computer with superconducting qubits is being able to integrate a sufficient density of microwave lines in a cryogenic environment. Traditionally this has been limited by the pitch of SMA cables. When trying to go beyond this approach there are two problems to address. The first is outfitting a dilution refrigerator with enough lines to run from room temperature to the base temperature stage. The second is building a package for a quantum integrated circuit that houses enough microwave lines itself. We propose a solution to both of these problems by using RF flexible circuits to increase signal density in the dilution refrigerator and package while maintaining signal integrity. We also discuss the thermal, mechanical and RF considerations that go into designing such a system. Finally we show a proof-of-concept integration of the entire system including measurements with superconducting qubits.

We report an ultra-wideband and high efficiency sub-6GHz power amplifier, which is based on periodically varied load modulation with frequency. Key novelties are frequency-periodic load modulation over multiple contiguous frequency bands combined with digitally assisted dual-input configuration, which provides optimum signal combination, magnitude and phase of dual-input signals. The amplifier using 0.15-µm GaN HEMT FETs achieved drain efficiency of 45-62% over 1.4-4.8GHz that is 110% fractional bandwidth at 6dB power back-off. This, to the best of the authors’ knowledge, is the widest fractional bandwidth reported so far for a load modulated amplifier at these frequency range. It is a very promising PA technology for 5G base station, enabling reduction of the total cost of ownership (TCO) for operators.

A compact microstrip varactor-based diplexer with six tunable channels is proposed. Each output path contains only two varactor-loaded multi-mode resonators, by which three two-pole passbands/channels can be independently and continuously tuned over a wide bandwidth. Given the input return loss greater than 10 dB and output isolation greater than 26.1 dB, the six channels of the fabricated diplexer can be experimentally tuned in the range of 1.16~1.36, 1.65~1.81, 2.05~2.36, 2.57~2.86, 3~3.52, and 3.3~3.89 GHz, respectively.

Eye diagram and its parameters measurement are very important to represent and analyze the high-speed digital signal. In this paper, K-means algorithm, which is popular in data mine, is introduced into the eye diagram parameters measurement. With the advantage of K-means algorithm, the method proposed in this paper can work automatically and effectively. A differential line is measured by vector network analyzer (VNA) and several eye diagrams at different data rates are generated by the measured S parameters. The method is used to measure these eye diagrams. Experiment results show that this method works very well.
