Description


The tuning range of commercially available DVB-T receivers includes the complete UHF-band up to channel 69.  The spectrum of 790 MHz up to 862MHz(channels 61-69)was made available for harmonized use of wireless broadband services. But those services may have an impact on the reception of DVB-T channels 52-60. In order to minimize this impact blocking-filters will be applied that significantly attenuate the signals of LTE800 base stations and user equipment as well.

 

The LTE-Filter SIAM790 and SIAM 782 reduces the LTE800 signals by more than 28dB. The complete LTE800 downlink and uplink band is strongly attenuated which means the potential impact of LTE transmitters is decreased efficiently.
