  • Front end communications system using RF mem switches
    Publication number: 20020151281
    Abstract: A front end module (10, 30) for a low weight, low power communications system. The front end module (10) utilizes RF microelectromechanical (MEM) switches (16, 18, 20, 110, 112, 156) for dynamic reconfiguration capability. Components (12, 14, 22, 24, 26, 28) are shared for both the transmit and receive modes, thereby reducing the number of components required by the system (10, 30).
