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.
Long-Term Evolution (LTE)
A wireless broadband communication standard for mobile devices and data terminals, based on
the GSM/EDGE and UMTS/HSPA technologies.
LTE-M
An open standard that is most suitable for medium throughput applications requiring low power,
low latency, and/or mobility, like asset tracking, wearables, medical, POS, and home security
applications. Also known as Cat-M1.
Mass Storage Device (MSD)
Any storage device that makes it possible to store and port large amounts of data in a permanent
and machine-readable fashion.
nRF Cloud
Nordic Semiconductor's platform for connecting IoT devices to the cloud, viewing and analyzing
device message data, prototyping ideas that use Nordic Semiconductor chips, and more. It includes a
public REST API that can be used for building IoT solutions. See
.
Operational Amplifier (op-amp)
A high-gain voltage amplifier that has a differential input and, usually, a single output.
Printed Circuit Board (PCB)
A board that connects electronic components.
Receive Data (RXD)
A signal line in a serial interface that receives data from another device.
Request to Send (RTS)
In flow control, the transmitting end is ready and requesting the far end for a permission to transfer
data.
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.
Serial Wire Debug (SWD)
A standard two-wire interface for programming and debugging Arm
®
CPUs.
Subscriber Identity Module (SIM)
A card used in
containing data for subscriber identification.
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.
