Band-pass filter

A band-pass filter or bandpass filter (BPF) is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range.

See RF and microwave filter and Band-pass filter

Band-stop filter

In signal processing, a band-stop filter or band-rejection filter is a filter that passes most frequencies unaltered, but attenuates those in a specific range to very low levels.

See RF and microwave filter and Band-stop filter

Coaxial

In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis.

See RF and microwave filter and Coaxial

Coplanar waveguide

Coplanar waveguide is a type of electrical planar transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave-frequency signals. RF and microwave filter and Coplanar waveguide are Distributed element circuits.

Coupling coefficient of resonators

The coupling coefficient of resonators is a dimensionless value that characterizes interaction of two resonators.

Crystal oscillator

A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element.

See RF and microwave filter and Crystal oscillator

Cutoff frequency

In physics and electrical engineering, a cutoff frequency, corner frequency, or break frequency is a boundary in a system's frequency response at which energy flowing through the system begins to be reduced (attenuated or reflected) rather than passing through.

See RF and microwave filter and Cutoff frequency

Dielectric

In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field.

Diplexer

A diplexer is a passive device that implements frequency-domain multiplexing.

See RF and microwave filter and Diplexer

Duplexer

A duplexer is an electronic device that allows bi-directional (duplex) communication over a single path.

See RF and microwave filter and Duplexer

Electrical reactance

In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance.

Electronic filter

Electronic filters are a type of signal processing filter in the form of electrical circuits.

Extremely high frequency

Extremely high frequency is the International Telecommunication Union designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz).

See RF and microwave filter and Extremely high frequency

Hertz

The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second.

See RF and microwave filter and Hertz

High-pass filter

A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency.

See RF and microwave filter and High-pass filter

LC circuit

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together. RF and microwave filter and lC circuit are Analog circuits.

Low-pass filter

A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency.

See RF and microwave filter and Low-pass filter

Medium frequency

Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz).

Microstrip

Microstrip is a type of electrical transmission line which can be fabricated with any technology where a conductor is separated from a ground plane by a dielectric layer known as "substrate".

See RF and microwave filter and Microstrip

Microwave

Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves (as originally discovered) but longer than infrared waves.

See RF and microwave filter and Microwave

Piezoelectricity

Piezoelectricity is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress.

See RF and microwave filter and Piezoelectricity

Planar transmission line

Planar transmission lines are transmission lines with conductors, or in some cases dielectric (insulating) strips, that are flat, ribbon-shaped lines. RF and microwave filter and Planar transmission line are Distributed element circuits.

Printed circuit board

A printed circuit board (PCB), also called printed wiring board (PWB), is a medium used to connect or "wire" components to one another in a circuit.

Q factor

In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is.

See RF and microwave filter and Q factor

Radio frequency

Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around.

See RF and microwave filter and Radio frequency

ResearchGate

ResearchGate is a European commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators.

See RF and microwave filter and ResearchGate

Resonance

In physics, resonance refers to a wide class of phenomena that arise as a result of matching temporal or spatial periods of oscillatory objects.

See RF and microwave filter and Resonance

Resonator

A resonator is a device or system that exhibits resonance or resonant behavior.

See RF and microwave filter and Resonator

Selectivity (radio)

Selectivity is a measure of the performance of a radio receiver to respond only to the radio signal it is tuned to (such as a radio station) and reject other signals nearby in frequency, such as another broadcast on an adjacent channel.

See RF and microwave filter and Selectivity (radio)

Stripline

In electronics, stripline is a transverse electromagnetic (TEM) transmission line medium invented by Robert M. Barrett of the Air Force Cambridge Research Centre in the 1950s.

See RF and microwave filter and Stripline

Surface acoustic wave

A surface acoustic wave (SAW) is an acoustic wave traveling along the surface of a material exhibiting elasticity, with an amplitude that typically decays exponentially with depth into the material, such that they are confined to a depth of about one wavelength.

See RF and microwave filter and Surface acoustic wave

Thin-film bulk acoustic resonator

A thin-film bulk acoustic resonator (FBAR or TFBAR) is a device consisting of a piezoelectric material manufactured by thin film methods between two conductive – typically metallic – electrodes and acoustically isolated from the surrounding medium.

Waffle-iron filter

A waffle-iron filter is a type of waveguide filter used at microwave frequencies for signal filtering.

Wi-Fi

Wi-Fi is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.
