How does an IQ modulator work?
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.
Why do we use IQ samples?
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 transmitter?
The IQ Base™ transmitter is a fast and reliable pager transmitter designed to work with all JTECH pagers and is is beautifully designed with an 8-line LED back lit interface and quick setup. With UHF frequency, your signal has a unique system ID which eliminates interference.
