It also contains the proprietary ADX technology which corrects mismatch errors in time-interleaved analog-to-digital converters (TI-ADCs) and thereby ensure industry-leading spurious-free dynamic range (SFDR). The digital signal processing also helps reduce the data rate to a manageable level in order to simplify data post-processing and storage. ADX corrects TI-ADC offset, gain and phase errors so that unwanted image spurs does not limit achievable SFDR. FW2DDC contains two digital downconverters (DDCs) consisting of quadrature mixers and decimation filters that help reduce the data rate, improve the signal-to-noise (SNR) ratio for the band of interest, and translate the RF frequency to an intermediate frequency (IF) for baseband processing. The subsequent finite impulse response (FIR) filters can be used either for further noise reduction, for channel equalization, or for correcting in-phase and quadrature (IQ) imbalance.
