ABSTRACT
In this paper, we demonstrate quality factor (Q) enhancement
of a silicon RF MEMS resonator by cryogenic cooling from room
temperature down to liquid nitrogen temperatures (78K). The
resulting Q is approximately 63,000 at a frequency of 3.72 GHz,
yielding an f-Q product of 2.34×1014
Hz. This work verifies that the
resonator is operating in the Landau-Rumer regime at room
