DDF-3101 2 x 2 Output 75 Ohm Passive Splitter, 34/45/270Mb/s
RWA-4300   Reverse Path Amplifier
 

DDF-3101  Dual Passive Splitter

Features

 
  • Dual 2 way RF splitters.
  • Operates in the frequency range of 0.25 MHz to 300 MHz.
  • Suitable for 34/45/270 Mb/s data rates.
  • No power required – totally passive.
  • Connections made by BNC connectors.
  • May be mounted in the same frame as other IRT Eurocards including VDA’s, ADA’s, detectors and processors.

General

The DDF-3101 is a dual 2 way RF splitter in a standard 3 RU Eurocard format. As such, it can be mounted in the same frame as other IRT Eurocards including VDA's, ADA's, detectors and processors.
It is primarily intended for use as a passive splitter for splitting data streams.
Each of the RF splitters is rated for 250 kHz to 300 MHz operation and is suitable for 34, 45 or 270 Mb/s data rates.

The DDF-3101 is a passive unit that requires no power to operate.
The DDF-3101 comes with a rear connector panel comprising of 75Ω BNC input and output connectors.

  RWA-4300  Reverse Path Amplifier

Features

  • 2 - 200 MHz frequency response specially contoured for
    use in reverse path of cable TV distribution.

  • Very low noise.

  • 0 - 20 dB variable input gain control.

  • Local or remote muting.

  • Input and output monitoring on front panel.

  • Power loss alarm output.

General

The RWA-4300 has been designed to provide amplification of signals in the reverse path of cable TV distribution systems.
An input attenuator with a 20 dB range provides gain control to optimise signal levels at the output.

Due to the high levels of RF noise in the operating environment the frequency response of the amplifier is tailored to give optimum low noise amplification to the reverse path signals, which normally lie between 5 and 100 MHz.

In addition the RWA-4300 is constructed with a high level of RF shielding which eliminates both ingress and egress of unwanted RF signals.
The FRU-4300 allows 8 RWA-4300’s to be mounted in one 3 RU frame together with two PSU’s which may be either 240 Vac or -48 Vdc.
