Penta Laboratories, a manufacturer in Newbury Park, Calif., makes vacuum tubes for radio transmitters and other purposes.

65 years ago, this ad appeared in Electronics Weekly’s edition of April 26th 1961: Keep up with developments relating to space technology - satellite technology, PNT, thermal imaging, SatIoT, ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

The magnetic loop antenna is a familiar sight in radio amateur circles as a means to pack a high performance HF antenna into a small space. It takes the form of a large single-turn coil made into a ...

A capacitor, along with resistors and inductors, belongs to a group of components known as passive devices. These components do not produce or amplify energy; instead, they can only store, absorb, or ...

Abstract: Resonant power inverters are among the most efficient power conversion topologies. However, their widespread adoption is hindered by inefficient operation and control limitations under light ...

Abstract: This letter presents an analog–digital variable capacitor realized by monolithic integration of barium strontium titanate (BST) ferroelectric material and phase change material (PCM) ...

Our fundamental passive and inherently analog components—resistors, capacitors, and inductors—are so conceptually simple and easy to describe that we often don’t fully articulate or appreciate the ...
