Dielectric targets mobile receivers
Dielectric Communications will display several new innovations in mobile data transmission at the NAB2008 show (booth #C1918).
The company will demonstrate its solutions for the mobile media market, with antennas, filters, and other components designed specifically for broadcasters who are transmitting content to wireless handheld devices via the 700MHz spectrum.
Among the new offerings on display is Dielectric's new 700MHz Stringent Mask band pass filter, which provides a cost-effective solution for broadcasting to portable devices. This new filter is based on the company’s specialized design techniques, which provide superior electrical performance with extremely low insertion loss compared with other filters of this size. The filter exhibits less than 0.6dB of integrated insertion loss over the band.
The 700MHz DR filter provides up to an 800W power capacity in a rack-mountable, compact design. Dielectric also offers an option to integrate other typical system components (such as couplers or harmonic filters) to create a complete RF system in a 3RU space.
The company’s new 150W repeater filter provides a compact, cost-effective component for broadcasters working in the 700MHz spectrum. The filter supports up to 150W of power and exhibits less than 1.5dB of integrated insertion loss over the band. Because the unit is rack-mountable, it integrates easily with other existing components to create a complete RF system.
Dielectric’s full line of TV antennas now includes a high-power, broadband UHF elliptically polarized panel antenna, which offers a variable polarization ratio from 0 to 100 percent while maintaining a high-quality axial ratio.
