Anode

An anode is an electrode of a polarized electrical device through which conventional current enters the device.

See Varicap and Anode

BC548

The BC548 is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment.

See Varicap and BC548

Capacitance

Capacitance is the capability of a material object or device to store electric charge.

See Varicap and Capacitance

Capacitor

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. Varicap and capacitor are capacitors.

See Varicap and Capacitor

Cathode

A cathode is the electrode from which a conventional current leaves a polarized electrical device.

See Varicap and Cathode

CMOS

Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss") is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

See Varicap and CMOS

Depletion region

In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region, or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have diffused away, or forced away by an electric field.

See Varicap and Depletion region

Diffusion capacitance

Diffusion Capacitance is the capacitance that happens due to transport of charge carriers between two terminals of a device, for example, the diffusion of carriers from anode to cathode in a forward biased diode or from emitter to base in a forward-biased junction of a transistor.

See Varicap and Diffusion capacitance

Diode

A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance). Varicap and diode are diodes.

Electronic article surveillance

Electronic article surveillance (EAS) is a type of system used to prevent shoplifting from retail stores, pilferage of books from libraries, or unwanted removal of properties from office buildings.

Electronics

Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles.

Frequency multiplier

In electronics, a frequency multiplier is an electronic circuit that generates an output signal and that output frequency is a harmonic (multiple) of its input frequency.

Mobile phone

A mobile phone or cell phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone (landline phone).

Monolithic microwave integrated circuit

Monolithic microwave integrated circuit, or MMIC (sometimes pronounced "mimic"), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz).
