This paper presents a 24-bit 5.0 GHz ultrahigh-speed direct digital synthesizer (DDS) with direct digital modulation capabilities used in a pulse compression radar. This design represents the first DDS RFIC in over-GHz output frequency range with direct digital modulation capabilities. It adopts a ROM-less architecture and has the capabilities for direct digital frequency and phase modulation with 24 bit and 12 bit resolution, respectively. The DDS includes a 24-bit ripple carry adder (RCA… CONTINUE READING
