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

DC

Direct Current

Global Navigation Satellite System (GNSS)

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.

GNSS

GPIO

General-Purpose Input/Output

Global Positioning System (GPS)

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

GPS

High-Q

Quality factor of an inductor or capacitor defined as the relation between its reactance and series (parasitic) resistance.

L1 C/A

Global Positioning System (GPS) signal broadcast by GPS satellites.

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

MIPI RF Front-End Control Interface (RFFE)

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

MIPI RFFE

Noise Factor (NF)

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

NF

Over-the-Air (OTA)

Refers to any type of wireless transmission.

OTA

Printed Circuit Board (PCB)

A board that connects electronic components.

PCB

Right Hand Circular Polarization (RHCP)

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

RHCP

Return Loss (RL)

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.

RL

Specific Absorption Rate (SAR)

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.

SAR

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

Signal-to-Noise Ratio (SNR)

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

SNR
