Claim Text:
1. A variable capacitor, comprising: a substrate; one or more bond pads disposed over the substrate; a first cell disposed over the substrate and coupled to the one or more bond pads, the first cell having a first end and a second end and comprising: an RF electrode coupled to the one or more bond pads and the first end of the first cell; a plurality of MEMS devices disposed over the RF electrode, each MEMS device having a first end and a second end and each MEMS device disposed over the RF electrode; and one or more ground electrodes coupled to the first end and the second end of each MEMS device and to the second end of the first cell; and a second cell disposed over the substrate and coupled to the one or more bond pads, the second cell having a first end and a second end and comprising: an RF electrode coupled to the one or more bond pads; a plurality of MEMS devices disposed over the RF electrode, each MEMS device having a first end and a second end and less than all of the total MEMS devices in the second cell are disposed over the RF electrode; and one or more ground electrodes coupled to the first end and the second end of each MEMS device and to the second end of the first cell.
