RF transceiver IC
An IC chip that takes the high-frequency radio signals transmitted or received through an antenna, such as those used in wireless systems, and modulates them to low-frequency signals. Also referred to as a RF front-end chip.
 CMOS technology
A logic circuit consisting of N-type and P-type metal-oxide semiconductors (MOS) with complementary connections formed on a silicon substrate. Attributable to their low power requirements, CMOS circuits are currently the mainstream for integrated circuits.
 Inductor element
In electromagnetic circuits, a passive element wound around an electric line that induces a voltage change in response to a current change.
 Baseband IC
In wireless systems, the logic chip that processes the data signal before it is demodulated or modulated to a high-frequency signal.
 Compound semiconductor
A semiconductor formed using two or more elements, such as gallium-arsenide (GaAs) or indium-phosphide (InP), and which features higher electron mobility than silicon, therefore permitting faster operation.
 Transmission line
In electronic devices and electronic circuits, an interconnect used to transmit a high-frequency signal. Some examples are waveguides, coaxial lines, and microstrip lines, among others.
