Digital Equalization of mmWave Analog Frequency Up and Down-converters

It is a known fact that time interleaving of Analog-to-Digital Converters (ADC) is used to increase sampling rate of modern high-performance digitizers. A recent high performance example is the 10-bit digitizers from Guzik Technical Enterprises (GTE) that feature Keysight Technologies ADC Integrated Circuit (IC) where 160 individual ADC are interleaved to achieve sampling at up to 64 Gsa/s (160 “slices” sampling at 400 Msa/s) forming two analog channels at 32 Gsa/s each.
