A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a ...

In this article, we propose and evaluate a direct antenna modulation (DAM) system. We attempt to bypass the upper bound on an efficiency bandwidth product (EBP) for an electrically small antenna (ESA) ...

The market for varactor diodes is segmented by type, application, and geography. The types of varactor diodes include Silicon, Gallium Arsenide (GaAs), and Silicon Germanium (SiGe) diodes. The ...

Three Primary Functions of a Diode When considering what is a diode, it's important to recognise its three primary functions: rectification, regulation, and signal demodulation. Each of these ...

Trapezoidal geometry was chosen due to the good resonant frequency reconfiguration sensitivity when the varactor diode present between the resonators has its capacitance changed due to the application ...

The VCO clearly shows that the oscillation frequency of the output waveforms is exponentially increased with an increase in the input direct current voltage, whose behavior is the same as a varactor ...
