 August 20, 2012 Press ReleasePublic Safety Broadband:
Another Job for Cavity Bandpass Filters
The drive to create a nationwide 700 MHz public safety broadband
network finally appears to have some teeth thanks to its inclusion in the Middle Class Tax Relief and Job Creation
Act of 2012. The law reallocates 10 MHz of spectrum in the infamous “D-block” to public safety, which along with
an existing 10 MHz of spectrum currently held by the Public Safety Spectrum Trust (PSST) will create 20 MHz of
spectrum dedicated exclusively to public safety data communications throughout the nation. LTE will be the
transmission technology of choice.
 A close look shows just how close these allocations are to each other and the miniscule guard bands that separate them, making the potential for interference to each other and to Verizon’s LTE network in the middle a distinct possibility. Consequently, the venerable cavity bandpass filter, with its exceptional selectivity, will once again be called upon to provide the solution, as it has for decades. Cavity filters – and good design practices – are the only solutions for caging the looming interference monster. The emerging public safety network will need cavity filters with signal rejection of -40 dB or more at 700 kHz from the various band edges.; Fortunately, cavity filters with this level of performance, along with low VSWR and insertion loss, high isolation, very low passive intermodulation distortion, high power handling ability, and ruggedness, have been one of the greatest strengths of Anatech Electronics or more than 20 years. Indoors or outdoors, they perform flawlessly.; So whether you’re part of the emerging public safety broadband initiative, or fending off interference in deploying LTE or other wireless networks, our cavity bandpass filters should be your first choice.
