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) ...
There is thus potential to see an EBP that exceeds the limitation for an antenna of a given size. The proposed antenna is based on a top-loaded monopole antenna and then utilizes varactor diodes to ...
ETX includes a digital direct-to-channel FM modulator and hot-pluggable power supplies. The control system provides monitoring, logging, and control capabilities.
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 ...
Inovonics’ fourth generation “541” FM Modulation Monitor is now shipping to customers. What makes it noteworthy compared to previous versions of the product?
A varactor diode or varicap diode is a semiconductor diode that changes its junction capacitance significantly depending on the applied reverse bias voltage.
The types of varactor diodes include Silicon, Gallium Arsenide (GaAs), and Silicon Germanium (SiGe) diodes. The applications of varactor diodes include tuning of RF circuits, frequency modulation (FM) ...
