The Flann Multihole Power Splitter consists of a central waveguide with coupling arrays in the broad walls designed to divide the input signal into three signals of equal magnitude.

Normally the instrument is a 4 port device as illustrated. However, for network analyser applications where only two equal amplitude signals are required the central output port may be terminated.

Precision machining methods ensure that the full band frequency sensitivity between secondary waveguide ports is better than ± 0.2 dB. The coupling to each output port is 4.8 dB down with respect to the input signal. Directivity for most models is greater than 40 dB.
