Glossary

The glossary contains terms and acronyms that are used in this document.

Band-Pass Filter (BPF)

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

BPF

Cat-M1

LTE-M User Equipment (UE) category with a single RX antenna, specified in 3GPP Release 13.

Cat-NB1

Narrowband Internet of Things (NB-IoT) User Equipment (UE) category with 200 kHz UE bandwidth and a single RX antenna, specified in 3GPP Release 13.

Clear to Send (CTS)

In flow control, the receiving end is ready and telling the far end to start sending.

CTS

DK (Development Kit)

A development platform used for application development.

DK

Fast Identity Online (FIDO)

A bundle of hardware and software modules serving as a tracing interface between traced device(s) and user application.

FIDO

Global Positioning System (GPS)

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

GPS

Hardware Flow Control (HWFC)

A handshaking mechanism used to prevent an overflow of bytes in modems. It is utilizing two dedicated pins on the RS-232 connector, Request to Send and Clear to Send.

HWFC

Inter-integrated Circuit (I2C)

A multi-master, multi-slave, packet-switched, single-ended, serial computer bus.

I2C

Low-Dropout Regulator (LDO)

A linear voltage regulator that can operate even when the supply voltage is very close to the desired output voltage.

LDO

Low-Noise Amplifier (LNA)

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

LNA

nRF Cloud

A cloud solution for visualizing data from Nordic reference designs. See nRF Cloud.

Operational Amplifier (op-amp)

A high-gain voltage amplifier that has a differential input and, usually, a single output.

op-amp

Receive Data (RXD)

A signal line in a serial interface that receives data from another device.

RXD

Request to Send (RTS)

In flow control, the transmitting end is ready and requesting the far end for a permission to transfer data.

RTS

SAW filter

A high-performing filter using Surface Acoustic Wave (SAW) technology. This technology employs piezoelectric transducers, which, when excited, produce waves that are used to filter out desired frequencies.

Surface Acoustic Wave (SAW)

An acoustic wave traveling along the surface of a material exhibiting elasticity, with an amplitude that typically decays exponentially with depth into the substrate.

SAW

System in Package (SiP)

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

SiP

System on Chip (SoC)

A microchip that integrates all the necessary electronic circuits and components of a computer or other electronic systems on a single integrated circuit.

SoC

Transmit Data (TXD)

A signal line in a serial interface that transmits data to another device.

TXD
