The design, fabrication, and characterization of micromachined RF passive c
omponents, including spiral inductors, Q- and L-enhanced inductors, and MIM
capacitors, monolithically realized on suspended membranes in an f(T) = 15
GHz silicon bipolar process (DIMES-03) are described. The performance of a
ctive inductors, active resonators, and oscillators incorporating suspended
-membrane components is compared to that of conventional MMIC circuit reali
zation. (C) 1999 John Wiley & Sons, Inc.
