Technology

The need for distribution or streaming information is increasing, and as a result, distribution technologies are being enhanced, and their functioning is being modified and improved on a continual basis. An amplifier that distributes a single computer, audio, or video signal to several devices while preserving signal integrity is known as a distributor (also known as a distribution amplifier or splitter).

What Is RF Signal Distribution?

An RF Distribution Amplifier is a strong performing distribution amplifier for analog radio frequency signals in radio frequency signals. It takes a single RF signal and distributes it to numerous outputs that are all identical. The use of a radio frequency distribution amplifier allows several stations to receive the same RF sine wave reference signal without degrading or interfering with it.

When radio frequency (RF) transmissions are used to transmit television and radio signals, they are dispersed throughout a facility to serve a large number of consumers. Fixed cables are one means of delivering radio frequency signals across a structure. Some situations, however, may need the use of a sophisticated network of cables and RF amplifiers, as well as splitters, switches, and other specialized equipment.

Importance of RF Signal Distribution

As many as 100 equipment stations may require a centralized reference signal, and this task can be onerous, especially if the signal must be sent without deteriorating or producing crosstalk. Many engineering and calibration labs, as well as production test facilities, run with this problem.

This is where RF signal distribution can help!

Streaming information with an RF Distribution Amplifier improves the possibilities of the audiovisual systems by:

  • Extending visual communication beyond the confines of a room or building to any location
  • Extending the system’s ability to scale and improve its overall performance
  • Streamlining the administration of cable infrastructure
  • Video, audio, and graphic data collected from various audiovisual sources are being recorded and analyzed

Each of these solutions has the potential to improve the effectiveness of the organization’s activities while also lowering the amount of money spent on capital investments in audiovisual equipment and running expenditures. We, at Tron Elektronik, provide all of the equipment required for the processing, distribution, and presenting of data. Signal processing and transmission are accomplished through the employment of cables, encoders, distribution amplifiers, distribution amplifiers, and other equipment.

Audiovisual and command signals are sent across vast distances by multi-output optical distribution amplifiers, which use optical fiber cables to do so. Video signals are disseminated through high-definition video players that are capable of playing back encoded video files in both 2D and 3D modes (speeds up to 250 Mbps). Players are perfect for use in entertainment and commercial applications where exceptional image quality is required to captivate an audience and create a favorable experience for the viewership. Super-widescreen and 3D displays may be shown using both video player playback channels, which can be controlled individually or synchronized.

Encoders are devices that allow high-resolution video to be sent in real time over regular IP networks. When employed in real-time recording, streaming, and playback applications, it ensures that visual quality and resolution are maintained at the highest possible levels. In best quality applications with stringent quality requirements, such as simulation, command and control, remote cooperation with complicated computer visualizations, the equipment is ideal for use.

The strong performing recording and streaming processor captures and distributes audiovisual inputs and presentations in the form of live streaming or recorded media. It is possible to construct separate records from two different sources using such a processor, which also includes a versatile platform for automating system operation. Processors may stream and record information at the same time, and they can stream signals at multiple resolutions and bit rates at the same time, all while utilizing a variety of transport protocols and session management options.  The use of these technologies to show presentations to a larger audience is both cost-effective and connectivity-friendly.

Example of RF Distribution Amplifier

Using a single distribution amplifier model, you may distribute a sine wave signal ranging in frequency from 100 kHz up to 10 MHz to as many as ten sites while maintaining good channel-to-channel isolation and little additional phase noise. The device is contained in a handy 1U-high rack-mountable chassis that provides better than 100 dB of isolation between the unit’s four outputs. Up to ten units can be daisy-chained together to offer up to one hundred matching outputs, or one unit can drive another to provide practically endless expansion capability with little or no signal loss, depending on the configuration.

The distribution amplifier is made up of a group of RF amplifiers with extremely low phase noise that are all powered by a common input amplifier. External RF input signals are terminated in 50 W and buffered before being sent to a common bus, which in turn distributes them to the ten output amplifiers, each of which contains its own level detector. Each detector operates both an individual light-emitting diode (LED) and a summary fault detector, which transmits any faults to the summary fault relay and LED through an OR circuit connected to the individual LED.

Using a unity gain design, the distribution amplifier operates in the range of frequencies 0.1 to 10 MHz and delivers a 1 V RMS signal to a 50 W load at each of its four outputs. The needed input signal ranges from 0.9 to 1.5 V RMS into 50 W, and the input impedance may be switched between 50 W and high impedance depending on the requirements. The output signals have harmonic distortion of less than –40 dBc and non-harmonic distortion of less than –80 dBc, respectively. It is possible to achieve channel-to-channel isolation of higher than 100 dB. At 1 Hz and 10 kHz away from the carrier, the additive single-sideband phase noise in a 1 Hz bandwidth is better than –120 and –160 dB, respectively. The machine draws less than 10 watts from either a 120 or a 240-volt alternating current source and can operate in temperatures ranging from 0° to 55°C and non-condensing humidity levels ranging from 0 to 95 percent.

    Thank you for this post! I’ve been trying to convince my boss that we need to improve our RF signal distribution in house. He didn’t believe that we could use cable to improve radio frequency distribution. We’ll be in touch soon to order some RF distribution amplifiers
