Abstract
A monolithic S-band 6 bit digital attenuator with dynamic range of 31.5 dB and with low insertion loss and compact size has been designed, fabricated and tested. Result shows the exceptional performance with reference state insertion loss as low as 2.8 dB at 3.2 GHz and VSWR better then 15 dB over all attenuation state and frequencies. The chip has a total size of 5.0 × 2.5 mm2 and the technology used is 0.7 um GaAs MESFET (G7S) switch process.
