Abstract :
A GaAs phase generator ASIC has been developed using a 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 mu m 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 a standard 132-pin ceramic package. The phase generator has been successfully tested in a prototype synthetic aperture radar.<>
