A GaAs Phase Generator ASIC has been developed using GigaBit's SC10000 standard cell library which produces the quadratic phase necessary to generate a linear-FM chirp waveform. Fully functional chips have been fabricated using a 3-layer metal, 0.9 μm gate E/D-MESFET process. Measured maximum accumulation rates vary from 450 MHz to 590 MHz. The chip is fully ECL and TTL compatible and is packaged in GigaBit's standard 132-pin ceramic package. The phase generator has been successfully tested in a prototype synthetic aperture radar at Sandia National Laboratories. Sample rates as high as 800 Msamples/sec have been synthesized using two phase generator/sine ROM combinations in parallel driving a TriQuint TQ6112 DAC.
