Abstract
This study presents the design and simulation of a 6-bit digital step attenuator utilizing 0.15 um GaAs for phased-array radar applications. The designed attenuator has a bandwidth of 1 GHz to 12 GHz. It has an LSB of 0.5 dB and a dynamic range of 31.5 dB. In addition, in order to reduce insertion loss, the widths of series switches have been made larger. After EM simulation, the insertion loss is better than -5.2 dB over the whole frequency spectrum. Using ADS 2015, EM simulations have been conducted. According to the data, the root mean square RMS of the amplitude and phase is less than 0.4 dB and 2.4 degrees, respectively. The designed attenuator's occupied area is 3,9 mm2.
