The acquisition of the two privately held companies would give RF Monolithics a comprehensive suite of hardware, protocols, software and services to enable new wireless device applications and services, according to RF Monolithics.

RFM will offer the broadest range of radios, modules, and protocols in the industry and, to our knowledge, no one else combines such a broad line of wireless offerings with a value added application and services platform, said RF Monolithics chief executive David Kirk, in a statement.

At the end of 2005, Cirronet and Caver-Morehead had sales of $10.4m and $1.7m, respectively. Dallas, Texas-based RF Monolithics said it expects the acquisitions to contribute $14m to $16m of combined sales for its fiscal year 2007, ending August 31 next year.
