Product Overview

The EVAL-CN0243-EB1Z is an evaluation board described in the circuit from lab CN-0243, entitled "High dynamic range RF transmitter signal chain using single external frequency reference for DAC sample clock and IQ modulator LO generation". The combination of the ADRF6702 IQ modulator and the AD9122 16bit dual 1.2GSPS TxDAC has the dynamic range necessary for a modern high level QAM or OFDM based wireless transmitter. The dynamic range of this circuit is good enough to enable both ZIF (zero IF/baseband) and CIF (complex IF up to 200MHz to 300MHz). The AD9122 has the option of up to 8X interpolation, as well as a 32bit NCO for very fine IF frequency selectivity. Overall performance of a transmitter is highly dependent on the dynamic range of the components directly in the signal chain. In a mixed-signal transmitter using a DAC and IQ modulator, the noise floor and distortion characteristics of these components define the overall dynamic range of the signal chain.
