Description
Telewave.io 8 Channel Compact Distribution Panels 1RU, are 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.
A typical receiver distribution panel 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 over come splitting and cable losses.
Telewave.io 1R panels provide 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 multicoupling generally requires some type of filtering between the receiver panel and antenna. Telewave.io manufactures a wide range of high quality preselector systems for transmitters and receivers.
Telewave.io 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 insure 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.
The 1R series ships standard with an inline low noise bipolar preamplifier (except TT models). Optional items include PHEMT preamps for lower noise figure, high 3rd order intercept preamps for RF congested sites, redundant preamps for maximum reliability at remote sites, and broadband preamps for multi-band applications.
OPTIONS:
- RA: 0-10 dB step attenuator
- RTT: 1 amp meter movement & DC injector to power Tower Top Preamp.
NOTES
- All unused ports must be terminated with 50 ohms. TWL-01 terminating resistor is available for this purpose.
- Panel gain is measured from the input port to any output port. Gain is adjusted at the factory according to individual system requirements. Standard gain is 6 dB if not specified.
- Tuning range and bandwidth vary depending on frequency band and system components.
- Exact frequencies and system gain must be specified with order.
