Power splitter/combiner with three 120° phase offset outputs

[sph2020]

Hi there,

I am searching for a way to combine three input signals with 120° phase offset between individual signals at 1.5GHz.
Any idea on how this might be done or know a component that does exactly this?

Cheers,
sph

At 1.5 GHz a wavelength is 7.9 inches. By adding wire of a certain length you can introduce a proportionate amount of time delay. (2.6 inches for 120 degrees in theory).

Or perhaps a series capacitor to advance a sine wave signal. (You'll need two in a row because 90 degrees is the most you can obtain from one capacitor.)

Series inductor to delay the signal. Capacitor integrator to delay the signal. (Likewise two networks are necessary.)

you did not mention the bandwidth. that is a pretty important factor in giving you an answer
