Reconfigurable Circuit Elements
Novel RF MEMSAt the fundamental level, passive RF/microwave circuits and systems consist of switches, capacitors, inductors, transmission lines, and resonators. These devices/circuit elements were the first on which the impact and implications of RF MEMS were studied.
The MEM switch, in particular, due to its noninvasive properties (i.e., virtually ideal insertion loss and isolation [1]), may be considered the most fundamental building block, or single device, embodying reconfigurability. Thus, all other reconfigurable functions will simply embody an appropriately organized set of interconnected switches. In what follows, beginning with a function employing a single switch, we expose some of the ideas elicited by the study of MEMS-based reconfigurability.
