A Wideband 6-Bit Digital Attenuator in a GaAs pHEMT MMIC
A low insertion loss, wideband 6-bit digital step attenuator is implemented in the 0.25-μm GaAs pHEMT process. Modified π- or T-type attenuator structures are adopted to expand the operation frequency bandwidth and reduce the insertion phase violation. Furthermore, the through-wafer via (TWV) is ana...
