SaTCR-1

Satellite channel router

DATA BRIEF

DESCRIPTION

inputs and polarizations, and can be carried on a

single coaxial cable.

Relaying satellite signals from the rooftop dish to

multiple receivers around the home, Digital Video

Recorders (DVR) or throughout an apartment

block is an expensive proposition for system

installers. The SaTCR-1 satellite channel router

addresses this problem by combining up to eight

input signals onto a single cable. These signals

are then decoded by a corresponding number of

tuners, potentially distributed across many set-top

boxes.

Figure 1. Package: QFN36 (6 x 6 mm)

The SaTCR-1 device is intended for use in LNBs

or switchers in satellite receivers. The device shifts

the frequency of any input signal to a fixed

intermediate frequency. The output signal is band-

pass filtered generating a narrow band output.

By combining several SaTCR-1 devices,

corresponding number of sub-bands may be

generated and multiplexed together.

This composite band can be made of different

independent channels issued from different LNB
