Low-noise block gives Sharp a complete lineup of satellite receiver components, from small systems for single-family houses to modules for satellite systems supplying entire blocks of flats

The Type BS1R8IL500A Quattro low-noise block gives Sharp a complete line-up of satellite receiver components. The Japanese manufacturer is now offering the full range of LNBs from small systems for single-family houses to modules for satellite systems supplying entire blocks of flats. The new Quattro Band LNB is the right solution for the installation in larger homes and apartment buildings to manage satellite receiving functionality.

It offers four outputs: the first two for the low band with horizontal or vertical polarisation and outputs 3 and 4 for the high band, again with horizontal or vertical polarisation.

This means that the module supplies exactly the right signal for a multiswitch, which can then be used to supply a corresponding number of satellite receivers.

The frequency bands with this combination are selected via the DiSEqC switching signal from the connected satellite receiver.

In terms of the signal input, the Quattro Band LNB covers the full spectrum of satellite broadcasting frequencies from 10.7 to 12.75GHz.

Like all satellite receiver components from Sharp, the new LNB module has outstanding performance: the noise figure across the full bandwidth is only around 0.6dB with a phase noise of only -75dBc/Hz at 10kHz offset.

Despite the high technical performance, the costs for the Sharp Quattro Band LNBs are comparatively low, even during operation since the power consumption is as low as 290mA.

For smaller satellite receiving systems, the Sharp portfolio also offers quad, twin and single LNBs.

They provide the same high signal quality as the Quattro Band LNB and are already fitted with a corresponding multiswitch.

This means that, depending on the number of outputs, they can directly supply an antenna signal to up to four independent satellite receivers.

Samples of the new generation of Sharp LNBs are available from the Sharp sales offices and distribution partners.

Series production has already started for most of the models, although the production of the new universal single band LNB is only due to start in Q2 2007.
