RFI Four-Way Cellular Band Power Divider

Key Features

• N-Type

• Splitter/Combiner function

• Broadband 698-2700MHz covering multi-cellular bands

• Manufactured to a low PIM< -140dBc (3rd Order 2x43dBm carriers) rating

• IP65 ingress protection

• 4x N Female output.

Usage

• RFI Wilkinson-style power dividers/combiners are used in a variety of RF power dividing and combining applications

• Typically used in DAS (Distributed Antenna Systems) for distributing power throughout feeder cable networks

• Designed using Wilkinson or N-way styled cascaded broadband binary power splitting or combining techniques offering broadband capability with good splitter output/combiner input, port-to-port isolation.

Splitter

• The input signal is equally split into two output signals, each reduced by 3dB (i.e. halved) due to the 1:2 power division

• A small signal loss of 0.5dB is incurred as no RF device can operate at 100% efficiency

• When determining whether you can afford to split your signal, keep in mind that the signal will be halved between each device: the question to answer is - is your signal strong enough?

• In very low signal areas it's often advisable to use two antennas instead of a splitter.

Combiner

• While it is possible to sum two input signals with no loss, this can only be accomplished if the input signals are identical in phase and amplitude

• When two signals are completely out of phase (180 degrees) the signals will cancel completely, hence the statistical average for two unknown signals is a 3dB combination loss (i.e. reduced by half).
