I see some one used the attached circuit as a power splitter. It is ussd in a 900MHz RF system. I can not understand its principle. Would anyone pls. gives me some explainations on this circuit?
It is a lumped version of Wilkinson power divider. Instead of quarterwavelength lines inductors are used to provide 90 deg phase shift on the operating frequency. The divider can be very small as oposed to classical realization with transmission lines.

Hi, flyhigh,
I think you are tight. Attached figure is the actuaral circuit I saw. Attached another PDF file is an article about the Wilkinson power splitters. I agree with you that it is the Wilkinson powet splitter. But just as tyassin asked above. Where is the capacitors Cp in the fiugre? I think the capacitos in the attached figure is the dc-blocking capacitor. So where is the Cp?
