Design Theory of Equal Split Dual- Band Power Divider without Reactive Elements
Advanced Electromagnetics, 2022 In this paper, a design approach for getting dual-band working in a Wilkinson-based power divider (WPD) without adding any reactive elements or open- or short-circuited stubs is presented.

Compact Load Network Having a Controlled Electrical Length for Doherty Power Amplifier
IEEE Access, 2022 The load network of the carrier amplifier for the conventional Doherty power amplifier (DPA) consists of an impedance matching circuit, an offset line, and a $\lambda $ /4 transmission line (TL), so that the overall electrical length of the network can ...

GHz operation of a quantum point contact using stub-impedance matching circuit
Physics Open, 2023 Quantum point contacts (QPC) are the building blocks of quantum dot qubits and semiconducting quantum electrical metrology circuits. QPCs also make highly sensitive electrical amplifiers with the potential to operate in the quantum-limited regime. Though

Boosting electromagnetic wave absorption of Ti3AlC2 by improving effective electrical conductivity
Journal of Advanced Ceramics, 2023 Electromagnetic wave-absorbing (EMA) materials at high temperatures are limited by poor conduction loss (Lc). However, adding conductors simultaneously increases the conduction loss and interfacial polarization loss, leading to a conflict between ...

Electrical excitation and detection of magnetic dynamics with impedance matching [PDF]
Applied Physics Letters, 2012 Motivated by the prospects of increased measurement bandwidth, improved signal to noise ratio, and access to the full complex magnetic susceptibility we develop a technique to extract microwave voltages from our high resistance (∼10kΩ) (Ga,Mn)As microbars. We drive magnetization precession with microwave frequency current, using a mechanism that relies

Memristive Bio-Impedance Modeling of Fruits and Vegetables
IEEE Access, 2021 Recent works show that the plants can exhibit nonlinear memristive behavior when excited with low-frequency signals. However, in the literature, only linear bio-impedance models are extensively considered to model the electrical properties of biological ...
