RF5220

Satellite Channel Stacking Switch IC

The RF5220 is RF Magic’s third generation Satellite Channel Stacking™ Switch (CSS)™ IC. A single RF5220 supports two wide-band satellite inputs and two frequency division multiplexed (FDM) channels to be transmitted over a single coaxial cable from the roof to multiple set top box (STB) tuners in the home. In a typical system using RF Magic’s EZStack™, 2 ICs might operate in parallel to support 4 LNB satellite inputs and 4 unique, user-selected channels stacked within 950-2150 MHz for transmission down a single cable.

The RF5220 is a highly integrated, channel-agile BTS IC. It integrates a switch matrix, RF variable gain amplifiers with associated power detectors, image rejection mixers, programmable output amplifiers, on-chip VCOs and low noise PLLs with integrated loop filters into a single 68-pin QFN package.

Applications

• DBS Single Cable Low Noise Block Converters
• DBS Single Cable Band Translating Switches
