RF - IQ Demodulator Slide 19
To summarize, the key ADI IQ demodulator specifications include: excellent noise figure and noise figure under blocker performance, high IIP3 and very broad frequency ranges, excellent gain and phase balance between I and Q channel. There are evaluation boards available for all IQ demodulators and the product datasheets show full characterization data. ADI has also released a web tool called ADISimRF that allows the designer to cascade various RF building blocks and see how the overall system performance stacks up in terms of IIP3, noise figure, power consumption, and IIP2. ADISimRF can be downloaded at www.analog.com/adisimrf.
