A Tunable Active MMIC Time Delay for Communication Systems in SiGe BiCMOS Technology

This paper describes a monolithic tunable active time delay with variable gain, designed using monolithic-microwave integrated-circuit (MMIC) technology, targeting in 3.5-4.5GHz range with a low power consumption of 9.4mW. It is impossible to realize such great delays with ideal transmission line in...

Zusammenfassung:This paper describes a monolithic tunable active time delay with variable gain, designed using monolithic-microwave integrated-circuit (MMIC) technology, targeting in 3.5-4.5GHz range with a low power consumption of 9.4mW. It is impossible to realize such great delays with ideal transmission line in MMIC, because of the length required for the line. In this paper We present analytical and computer-simulated results using 0.35μm SiGe BiCMOS process for a tunable active time delay in 3.5-4.5GHz range. It works as a pure time delay over 800MHz frequency band.
