Multihole Directional Couplers Series 230 / 231

Features

• High Directivity
• 3 Way Signal Splitter
• ± 0.2 dB Balance Between Coupled Arms

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.

IMPORTANT! All directivities quoted include the measuring port and flange performance when connected to an ideal termination.
