- | >This receiver is a straight forward 300 MHz to 900 MHz receiver with no down conversion. Due to intensive RFI in this broad frequency band three filter bands are installed to prevent the system from sturation by the strongest interferer. Nevertheless there is much more RFI in the band that has to be filtered in the backend. For a dedicated project a switchable RF filter plus LNA has been inserted. The filter has a bandwidth of 7 MHz and its frequency is fixed from 399 to 406 MHz. For continuum measurements an analogue filtering down converter module to an IF of 100 MHz to 180 MHz for both channels is available: | + | >This receiver is a straight forward 300 MHz to 900 MHz receiver with no down conversion. Due to intensive RFI in this broad frequency band three filter bands are installed in the main part to prevent the system from saturation by the strongest interferer. Nevertheless, there is much more RFI in the band that has to be filtered in the backend. For dedicated projects, switchable RF filters plus LNAs have been inserted for frequencies around 402 MHz and 611 MHz. The filters have a bandwidth of 7 to 10 MHz.
