Description


Telewave Telewave 8 Channel Compact Distribution Panel 1RU, is used to feed multiple receivers from a common antenna, reducing cost and tower loading, while providing consistent signal quality, output isolation, and higher output levels. The multicoupler includes a power supply, inline low noise preamplifier, and one or two 8-way splitters all on a single 19" tray. The preamplifier provides as much as +18 dB system gain to overcome splitting and cable losses.

The Multicoupler provides full performance in only 1RU. The 8 channel unit can be easily field expanded to 16 channels, by adding an additional 8 channel splitter. All receiver panel components are fully shielded, and each panel has sufficient bandwidth to cover an entire commercial or Public Safety band. New panels can be directly coupled to existing panels without additional parts or tuning. Successful multi-coupling generally requires some type of filtering between the receiver panel and antenna.

Telewave receiver panels use high-quality splitters to provide 8 or 16 matched 50-ohm outputs from one input, with typical 25 dB isolation between ports. The antenna port is tuned with a matching network to ensure a balanced input.

These units, with their specially designed power supply, can be powered from an AC or DC source. The internal DC input circuitry will allow the external input DC voltage to vary between +11.5 VDC to +15 VDC, while keeping the DC output voltage constant. This feature allows the preamplifier to perform at its rated gain, 1 dB compression point, and 3rd order intercept point. This design is especially suited for battery, solar panels, and thermal generator sources. An external DC-DC converter allows operation from DC inputs as low as +9.5 VDC.
