Programming Cable
circuit board with copper strips on one or both
sides to replace wires.
Programming Cable
computer to communicate directly with certain
radios using USB.
Radio Frequency (RF)
electromagnetic spectrum between audio sound
and infrared light (approximately 10 kHz to 10
GHz).
Radio Frequency Power Amplifier
Amplifier having one or more active devices to
amplify radio signals.
Abbreviation: RFPA
Receiver
Electronic device that amplifies RF
signals. A receiver separates the audio signal
from the RF carrier, amplifies it, and converts it
back to the original sound waves.
Request-To-Send
In General Packet Radio
Service (GPRS), a handshaking signal used with
some communication links to indicate that data is
ready for transmission.
Abbreviation: RTS
RESET
Reset line; an input to the
microcontroller that restarts execution.
Signal
An electrically transmitted
electromagnetic wave.
SLIM
Slim Connector
Spectrum
Frequency range within which
radiation has specific characteristics.
Static Random Access Memory
RAM chip used for volatile, program/data
memory.
Abbreviation: SRAM
Subscriber Identity Module
that holds subscriber information (including the
authentication key) and is inserted into the radio
to grant its personality.
Abbreviation: SIM

A smart card
System-On-a-Chip
with all the required circuitry and components of
an electronic system on a single chip.
Abbreviation: SoC
Time Division Multiple Access (TDMA)
A channel access method to allow several
users to share the same frequency channel by
dividing the signal into different time slots
Transceiver
Transmitter-receiver: A device
that both transmits and receives analog or digital
signals.
Abbreviation: XCVR
Transmitter
Electronic equipment that
generates and amplifies an RF carrier signal,
modulates the signal, and then radiates it into
space.
Universal Serial Bus (USB)
bus standard that supports data transfer rates of
12 Mbps.
Voltage Controlled Oscillator (VCO)
An oscillator whereby the frequency of oscillation
can be varied by changing a control voltage.
An integrated circuit
An external
