US Patent 7429904 - MEMS spread spectrum transmitter

This is another patent from Avago Technologies related to their work on the use of MEMS oscillators in spread spectrum communications. Claim 1 reads:

1. A spread-spectrum transmitter comprising:

microelectromechanical systems (MEMS) based oscillation system comprising at least one MEMS resonator and being configured to generate signals at different frequencies; and

the MEMS based oscillation system further comprising a controllable switch configured to select one signal at a time within the MEMS-based oscillation system in response to a spread-spectrum code, the output from the controllable switch being a spread-spectrum signal.
