Abstract:
The design and measurement of 0.1 – 4.5 GHz 5-bit MMIC digital step attenuator (DSA) are presented. The MMIC DSA is fabricated with 0.25 um SiGe BiCMOS process and includes integrated driver providing serial/parallel control. The main features of MMIC DSA are as follows: wideband performances (it covers L-, S- and partially C-band); a good input and output return losses (less than 12 dB and 14 dB, respectively); small phase variation (RMS phase error less than 5.3°); integrated driver; small size (1.4×0.6 mm2); low power consumption Performances of MMIC DSA designed are compared with its commercial counterparts.
