radios using USB.
Radio Frequency (RF) The portion of the
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

electromagnetic wave.
SLIM Slim Connector
Spectrum Frequency range within which
radiation has specific characteristics.
Static Random Access Memory Static-
RAM chip used for volatile, program/data
memory.
Abbreviation:SRAM
Subscriber Identity Module A smart card
that holds subscriber information (including the
authentication key) and is inserted into the radio
to grant its personality.
Abbreviation:SIM
System-On-a-Chip An integrated circuit
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 signals.
Abbreviation:XCVR
Transmitter Electronic equipment that
generates and amplifies an RF carrier signal,
modulates the signal, and then radiates it into
space.
