Dual Band, Wilkinson RF Splitter
Chris Haji-Michael www.sunshadow.co.uk/chris.htm
This sheet is for a dual-band power-divider.
This is a Wilkinson power splitter that is designed to operate at two frequency bands.
The maths for this filter is from Cheng, Law, IEEE MTT issue 56/2 pages 487 onwards.
Inputs yellow, outputs green
Main user input area:
This should be between 1.3 and 2.7
Calculate:
The S21 and S31 are the same and shown below with 3dB loss each, which is expected.The isolation (S23) is quite interesting as it is more than 20dB down at both operating frequencies.Quite an impressive circuit.
