Abstract :
This paper describes MMIC digital attenuator with small phase variation in S-band. The five-bit digital attenuator employing SPDT switched circuits has obtained excellent performance. It has been shown that a minimum attenuation of 7.05 dB, r.m.s. amplitude error of 0.09 dB, and r.m.s. phase variation of 1.38 degrees were obtained
