Reconfigurable Filter Bank
- Eight 2 GHz channels
- 256 Filter states
- Fast, <100 ns switching speeds
- Low noise figure, 15 dB nominal
BSC have independently developed a fully reconfigurable adaptive filter solution, designed for fast & seamless switching into any of 256 filter states across the 2-18 GHz range. Ideally suited to EW front-end preselection or protection, any combination of bandpass and bandstop states can be selected INTRODUCTION. Each 2 GHz channel can be switched in (bandpass) and out (bandstop) of the signal path with a switching time of less than 100 ns. DC power and 8-bit TTL control is supplied through a standard 15-pin MDM connector. In the crowded spectrum of the future, front-end flexibility is of increasing importance. Not limited to 2-18 GHz or equal channel widths, the same core architecture may be used in more specific bands, for example at VHF/UHF frequencies. This makes the system equally as suited to EW as it is to Mil Comms applications, where sampling sensitivity or frequency-agile protocols respectively are key to system function.
