What does IQ stand for in RF?
Quadrature signals, also called IQ signals, IQ data or IQ samples, are often used in RF applications. They form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis.
What is IQ in DSP?
What does IQ stand for? The I stands for “in phase” and the Q stands for quadrature. By convention, the I signal is a cosine wave and the Q signal is a sine wave. Another way to say that is that the I and Q signals are 90 degrees out of phase.
What is IQ rate in communication?
IQ rate is the sampling rate of the baseband I/Q data in samples per second (S/s). Carrier frequency is the carrier frequency of the RF signal in Hz. Gain is the Tx gain applied to the RF signal in dB. Active antenna is the antenna port to use for this channel.
What is IQ modulation?
What's an IQ Modulator? An IQ modulator is a device that converts baseband information into RF signals. Internally, two double-balanced mixers are combined as shown below. By modulating with both in-phase (I) and quadrature (Q) inputs, any arbitrary output amplitude and phase can be selected.
