Four-Way RF Power Divider

Key Features

• N-Type

• Splitter/Combiner function

• 4x N Female output.

Usage

• Simultaneously connect two devices to the one antenna by splitting the antenna signal

• This is a high quality low VSWR, low insertion loss RF power divider

• When in weak signal strength areas it's important to use a high quality splitter to ensure efficiency losses are kept to a minimum, minimal electrical noise, and output isolation maximised

• Poorly designed dividers can result in a signal power reduction far greater than 3dB, and signal code power reduced by significantly more.

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)

• Utilising microstrip structure technology, this splitter has exceptional in-band flatness, high isolation, very low insertion loss, excellent standing wave performance and is easy to install

• Designed for cellular mobile communications and spread spectrum communications in indoor distribution system.
