Features
- High directivity
- Multi-hole coupling
- Balanced response between side-coupled arms
- Average three-way split over band
Flann’s multi-hole millimetric 3-way power splitters consist of a central waveguide with coupling arrays in the broad walls designed to divide the input signal into three signals of approximately 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.
These instruments are precision machined structures which ensure very close matching between the secondary waveguide ports over the full waveguide band, typically better than ± 0.3 dB up to 75 GHz and ± 0.5dB above 75 GHz. The coupling to each output port is, on average, approximately the same for a given instrument (waveguide size).
IMPORTANT! Quoted directivity assumes an ideal termination.
