  • Radio having a MEMS preselect filter
    Patent number: 7668505
    Abstract: The present invention provides systems and methods for pre-filter in a VHF receiver using Micro-Electro-Mechanical Systems (MEMS) filters. The system includes an antenna, and first and second Micro-Electro-Mechanical Systems (MEMS) filters. The first MEMS filter filters a signal received by the antenna based on a first pre-defined bandwidth, and the second MEMS filter filters the signal filtered by the first MEMS filter based on a second bandwidth. The system also includes an analog to digital converter that converts the signal filtered by the second MEMS filter into a digital signal, a down converter that down converts the digital signal produced by the A to D converter, and a digital signal processor that processes the down converted digital signal produced by the down converter. The first and second MEMS filters or the down converter are adjustable based on a received tuning signal.
