Microwave filters ease compliance to FCC's re-banding mandate

K&L Microwave Inc., part of Dover Corp.'s Microwave Products Group, has announced the availability of a family of microwave filters designed specifically to support OEMs' compliance with the U.S. Federal Communications Commission (FCC) mandate to relocate incumbent Broadcast Auxiliary Service (BAS), Cable Television Relay Service (CARS), and Local Television Transmission Service (LTTS) licensees operating within frequency ranges of 1,990-2,110MHz.

The 30-month frequency re-banding effort, which was launched in August 2004, will be conducted on a regional market basis starting with TV service providers in the most densely populated U.S. cities. It requires that all eligible licensees convert from the present 17MHz channel plan to a new FCC-mandated 12MHz channel plan that will operate from 2,025MHz to 2,110MHz.

"The re-banding issue came about as a result of signal interferences seen in lower frequency spectrums thus causing a need to vacate higher frequency spectrums to allow for operator separation," said John Griffith, strategic account manager for commercial products.

To help mitigate such potentially dangerous signal interference, K&L said it is offering broadcast engineers a family of high-quality, competitively priced microwave filters. The family features a full-band filter that passes from 2,025MHz to 2,110MHz, a narrow-band (12MHz-wide) channel filter that operates from 2,031.5MHz to 2,103.5MHz, and a high-pass filter that passes from 2GHz to 18GHz.

K&L can also customize the mounting configuration and packaging for each filter. For instance, the company can manufacture filters for operating environments beyond that of use within a remote vehicle. This includes reliable functionality for operation outdoors where resistance to rain, humidity and heat is essential.
