Two companies have notable advancements in the microelectromechanical systems (MEMS) industry. WiSpry Inc. has announced the success of its new antenna tuner, while SiTime Corp. has received backing from Vectron and Knowles.

WiSpry Inc. has announced its successful demonstration of its WS1033 antenna tuner which can be used to extend LTE bandwidth. The company's demonstration, which was based on an LTE smartphone, allowed operation from 25MHz window up to a 180MHz window (700MHz to 880MHz) without changing the antenna.

Jeffrey Hilbert, president and founder of WiSpry, stated that the demonstration proves that 700MHz LTE antennas which are tuned with their technology have excellent and constant radiation properties over an extremely wide bandwidth. He added that the WS1033 extended the 700MHz bandwidth more than seven times and enabled coverage from band XII through band V with no change to the antenna element. This finding should enable the creation of a true global LTE phone that consumers will come to demand.

The company also stated that the WiSpry WS1033 features both a MIPI Alliance interface and an SPI interface, which makes it plug-and-play compatible with major smartphone chipsets.

SiTime gets backing from Vectron, Knowles
SiTime has entered into a strategic partnership with Vectron International Inc. (Hudson, NH) and Knowles Electronics (Itasca Illinois), both owned by Dover Corp. of New York.

The partnership includes a cash investment in SiTime by Vectron, which is a maker of quartz timing products, and Knowles, which makes silicon membrane microphones. The size of the investment was not disclosed.

"Knowles Electronics has long been known as an innovator and a leader in MEMS microphones and we look forward to bring the same level of success to the SiTime family of MEMS timing products," said Jeff Niew, CEO of Knowles, in a statement.

Rick Hajec, President of Vectron International, added: "We have closely followed advancements in MEMS timing technology over the last decade and believe that SiTime's product performance is poised to disrupt the timing industry and enable new market growth. We are excited by the prospect of bringing this compelling technology to all of our customers around the world."

As part of the agreement, both Vectron and Knowles will sell MEMS timing products through their own direct sales channels, as well as support SiTime in future product developments.
