This paper examines a single-ended class-AB GaN HEMT RF high power amplifier that operates in sub-6 GHz FR1 5G frequency bands such as n40 (2300MHz), n41 (2500MHz), and n7 (2600 MHz). A broadband matching network utilized for both the input and output sides of the circuit, as well as a 2nd and 3rd harmonic tuned circuit has been added to minimize interference with the fundamental tones. During a two-tones test at f0 frequency 2500 MHz with a frequency offset of 10 MHz, the proposed design demonstrated a high OIP3 of more than 47 dBm. The proposed design was fabricated, and the results show reasonable agreement with the large-signal simulation results, with a maximum output power of 40.5 dBm and a drain efficiency of 67 percent at 2500 MHz and 400 MHz of bandwidth.

Filtering attenuators (filtenuators) combine the frequency selectivity of filters with the controlled loss of an attenuator in a single component. Often, the filtenuator is made of three resonators or less to minimize the complexity of the design and the resistive π-network distribution is straightforward. However, the resistive network distribution is less clear for high-order filtenuator designs. This paper presents an alternative method of loading a filtenuator that has more than three resonators and is compared to the traditional π-network method of loading a resonating circuit. A detailed analysis of the resistive network distribution is conducted to optimize the filter shape using a fifth-order Chebyshev bandpass filter topology. A 900 MHz fifth-order filtenuator with 6.5 dB of passband loss is designed using the optimized distribution method, and the measured results are compared to simulation.

The laser-enhanced direct print additive manufacturing (LE-DPAM) process is used to fabricate and characterize low temperature co-fired ceramic (LTCC) paste for high temperature applications. Coplanar waveguides (CPW) were used to characterize the performance of the additive manufactured LTCC substrate and the permittivity is extracted using direct S-parameters measurements up to 40 GHz. The extracted permittivity is calculated to be an average of 21.3 over 1–40 GHz. A 4 dBi mm-wave antenna is designed and fabricated to demonstrate the capability to additive manufacture LTCC materials, with resonances in the 32–34 GHz range which endured at temperatures up to 980 °C. To the authors’ best knowledge, this is the first fully additive manufactured solution for LTCC technology, where both LTCC and conductive traces were printed using a microdispensing AM process.

This paper discusses the limitations of current electronic solutions for integrated mm-wave transceivers that are suitable for 5G mobile communications and introduces silicon photonics (SiP) as an alternate solution to address these limitations. Also the issue regarding distorted initial responses of SiP circuits, such as tunable bandpass filters and true-time-delay units, due to process variation is discussed and automatic calibration techniques algorithms are proposed to alleviate this problem.

The field of inkjet-printed circuits and sensors has yet to reach commercial maturity but is showing significant success in research with ultra-low power, paper-thin, flexible and biodegradable devices that are magnitudes less expensive to fabricate than silicon-based circuits. One such implementation, as discussed in this work, is with capacitive-based sensors, where charge fluctuations in and around the plates’ gap region alter the output current signal. The resulting functionalities are vibration/proximity sensing, where the magnitude of the output current reflects the environmental perturbations. The power efficiency, flexibility, and cost effectiveness of the sensor as reported in this work demonstrates that simple fabrication with inkjet-printing can form green-friendly, high-functioning devices as alternatives to standard silicon-based approaches. Silver nanoparticle ink was inkjet-printed onto a PET film substrate with the design of two parallel plates with a narrow gap region between them that is cut and filled with hexagonal boron nitride nanoparticle ink, which is a dielectric and charge trapping material. Fringe-field capacitance emanating from the flat substrate around the gap region of the parallel plates fluctuates according to the vibration and proximity of environmental interference. The sensor operates at an average of 4.9 nano-Watts with a 3.3V supply, senses floor/table vibrations from 5 feet away, costs $0.19 to fabricate, and is compatible with additive manufacturing for high-volume printing. Applications include movement detection near irregularly shaped surfaces, touch-less interfaces for initiating devices, traffic monitoring and prediction with post-processing algorithms, and high-volume deployment for large-area vibration observations.

Due to the fast growth of diverse wireless network deployments, the radio spectrum is becoming scarce. Hence, it is beneficial that different radio access technologies share the spectrum in a harmonious way. In this paper, we propose a co-existence scheme between Long Term Evolution (LTE) and Wi-Fi networks that utilizes a Multimedia Broadcast Multicast Service (MBMS) over a Single Frequency Network (MBSFN) feature of an LTE network. MBSFN is an LTE feature that provides support for multicast/broadcast traffic. We propose an adaptive scheme that configures muted subframes, initially intended for MBSFN operation, to allow Wi-Fi transmissions. For the adaptive configuration of muted MBSFN subframes, the LTE eNB uses its traffic queue and the Wi-Fi spectrum occupancy information, which is determined by a convolutional neural network-based technology recognition and traffic characterization system. The standard LTE System Information Blocks are used to convey the updated configuration to the LTE UE. Hence, the proposed coexistence scheme doesn’t require any modifications to a standard MBSFN-compliant LTE UE. Performance analysis is done for various traffic situations, and the results show that muted MBSFN subframe-based coexistence gives a 15% improvement in average aggregated throughput as compared to using Almost Blank Subframe-based coexistence.

A two-phase measurement method is presented to evaluate Bluetooth low energy (BLE) modules’ vulnerability to electromagnetic side-channel analysis attacks. In both phases, signals are collected by probing the fields near the surface of a chip that operates as a generic attribute profile (GATT) server, while it receives and processes data via Bluetooth. In Phase I, first optimal measurement configurations—time intervals, probe positions, probe orientations—are identified by computing the analysis-of-variance (ANOVA) F-statistic on signals collected from a multitude of such configurations while a few carefully chosen data are repeatedly sent to the GATT server. Then, these configurations are used to construct a reference database by collecting additional signals as specific additional data are sent to the GATT server. In Phase II, the chip is monitored using the optimal measurement configurations and the collected signals are compared to those in the database to extract the data. This side-channel analysis attack is shown to recover the Hamming weights of arbitrary data sent to the GATT server with ~99% success rate.

Two-phase flow monitoring is widely present in various industrial processes. The most popular methods used to estimate flow parameters can be divided into the noncontact and the contact -based modalities. Conductance-based and capacitive sensors are the most popular contact-based techniques used to provide flow parameter estimations. Among the noncontact sensors, optical-based systems are commonly utilized for multiphase flow classification. However, contact-based systems require specific proprieties from the analyzed fluid mixture such as high conductivity or low conductivity and they must be attached to the tube, so accurate measurements can be provided. On the other hand, optical devices lack robustness against ambient light conditions and might require complex computational processing pipelines. In this work, gas-liquid two-phase flow monitoring based on radar technology is proposed. Characteristic flow velocity distributions associated with different two-phase flows are remotely recognized by studying the reflected sub-THz signals that are phase-modulated by the moving gas-liquid interface. Experimental results confirm the feasibility of the proposed scheme for the identification of different gas-liquid two-phase flows using sub-THz radar imaging.

This paper aims in analyzing the performance of the New Radio (NR) technology introduced by the Third Generation Partnership Project (3GPP) for Vehicle-to-everything (V2X) communication. The NR system is believed to be a complementary service for the already existing Long Term Evolution (LTE) Cellular-vehicle-to-everything (C-V2X) for advanced services in vehicular communications. The 5th generation (5G) NR systems are believed to outperform LTE C-V2X in terms of providing high throughput, low latency, and high reliability in dense traffic situations. Our aim in this paper is to implement and analyze the 5G NR V2X open source module in network simulation-3 (ns-3) and then to demonstrate the NR V2X performance in terms of different key performance indicators by varying a number of situations, including transmit power, communication range, packet size and sub-carrier spacing in the broadcast channel.
