Digital chirp synthesizer

摘要

A monolithic digital chirp synthesizer (DCS) chip using GaAs/AlGaAs HI2L technology. The 6500 HBT gate DCS chip is capable of producing linear frequency modulated (chirp) waveforms or single frequency waveforms. The major components of the DCS are two pipelined accumulators, a sine ROM, a cosine ROM and two digital to analog converters.
