Patent ID: 8350642

Claim:
A system comprising: a front-end interface device including a first front-end interface port, a second front-end interface port and a third front-end interface port, the front-end interface device being configured to split a first signal directed into the first front-end interface port into a second signal provided at the second front-end interface port and a third signal provided at the third front-end interface port, the first signal having a first bandwidth, the second signal having a second bandwidth and the third signal having a third bandwidth, the second bandwidth being substantially disposed in a relatively high frequency portion of the first bandwidth and the third bandwidth being substantially disposed in a relatively low frequency portion of the first bandwidth; an N-way high-band device including a first high-band device port coupled to the second front-end interface port and N second high band ports, N being an integer greater than or equal to two (2), the N-way high-band device being configured to split the second signal into N-high band signals and direct the N-high band signals out of corresponding ones of the N-second high band ports; an N-way low-band device including a first low-band device port coupled to the third front-end interface port and N-second low band ports, the N-way low-band device being configured to split the third signal into N-low band signals and direct the N-low band signals out of corresponding ones of the N-second low band ports; a delay element substantially disposed between the front-end interface and the N-way low-band device or the N-way high-band device; a phase correction element disposed between the front-end interface and the N-way high-band device or the N-way low-band device; and N back-end interface devices coupled to the N-way high-band device and the N-way low-band device, each back-end interface device of the N back-end interface devices including a first back-end interface port coupled to a corresponding one of the N second high band ports, a second back-end interface port coupled to a corresponding one of the N second low band ports, and a third back-end interface port, each back-end interface being configured to combine one of the N-high band signals and one of the N-low band signals to form a fourth signal directed out of the third back-end interface port such that N-fourth signals are directed out of the N back-end interface devices, the fourth signal having a fourth bandwidth, the fourth signal being a version of the first signal such that the fourth bandwidth and the first bandwidth are substantially identical.
