An S/C/X-Band 4-Bit Digital Step Attenuator MMIC with 0.25 μm GaN HEMT Technology

In this paper, a 4-bit digital step attenuator using 0.25 μm GaN HEMT technology for wideband radar systems is presented. A switched-path attenuator topology with resistive T-type attenuators and double-pole double-throw (DPDT) switches was used to achieve both low insertion loss and phase/amplitude...
