26.5-GHz MEMS Switch Offers Low Loss, High Linearity

Using its proven MEMS manufacturing technology, TeraVicta Technologies Inc. has created the dc to 26.5-GHz SPDT MEMS switch, the TT1244. The new switch leverages the baseline process and design technology of the company’s dc to 7-GHz switch, which is already in production, and offers a step-improvement in bandwidth and linearity over competing solutions, while occupying significantly less area and consuming less power. The TT1244 delivers improved system performance, with a low insertion loss (from 0.1 dB at dc to 1.8 dB at 26.5 GHz) and very good linearity (greater than 75 dBm IP3).

Isolation ranges from 60 dB at dc to 20 dB at 26.5 GHz. The device comes in a standard surface-mount microBGA chip-scale package. Typical applications include automated test equipment, instrumentation, automotive and military radar, and communications infrastructure. An evaluation board—the TT1244AD-EB—is available through TeraVicta and Richardson Electronics for $995 each. The TT1244AD MEMS switch costs $92.00 each in sample quantities and $49.75 each in quantities of 1000. Samples are available now through TeraVicta. To learn more, go to www.teravicta.com.
