The power of an IQ signal is the squared magnitude, I2+Q2.
What is I and Q in RF?
By convention, the I signal is a cosine waveform, and the Q signal is a sine waveform. As you know, a sine wave (without any additional phase) is shifted by 90° relative to a cosine wave. Another way to express this is that the sine and cosine waves are in quadrature.
What is I & Q data?
I/Q data is an alternative method of describing the magnitude and phase data of a signal. A sinusoidal wave can be written in polar coordinate form as shown in the following equation: f(t) = Acos(2 ft + φ) where. A is the amplitude.
What is IQ data in radar?
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 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.
