Glossary

An electronic device or circuit that passes frequencies within a certain range and rejects frequencies outside that range.

A non-cellular radio standard included as part of the 5G standards by the ITU.

A hardware development platform used for application development.

A sudden discharge of electric current between two electrically charged objects.

A satellite navigation system with global coverage. The system provides signals from space transmitting positioning and timing data to GNSS receivers, which use this data to determine location.

A satellite-based radio navigation system that provides its users with accurate location and time information over the globe.

In a radio receiving system, an electronic amplifier that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio.

A dedicated control interface for the RF front-end subsystem. MIPI Alliance

The relation of the Signal-to-Noise Ratio (SNR) in the device input to the SNR in the device output.

Refers to any type of wireless transmission. For Matter, OTA is synonymous with the Over-the-Air software update mechanism.

A board that connects electronic components.

The relation of incident power to reflected power typically expressed in dB. High return loss corresponds with low reflected signal level and good impedance matching.

Circular polarization in which the electric field vector rotates in a right-hand sense with respect to the direction of propagation.

The level of signal power compared to the level of noise power, often expressed in decibels (dB).

The rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field or other forms of energy.

Several integrated circuits, often from different technologies, enclosed in a single module that performs as a system or subsystem.

The minimum received power at which a radio receiver can detect a signal with a specified bit error rate when the signal is arriving equally from all directions.

The sum of all power emitted by an antenna in all directions, accounting for any losses in the transmission process.
