A power amplifier yields 10 watts over 8-14 GHz using GaAs MMICs in an LTCC serial combiner/divider network

An effort was made to develop a high-efficiency N-way combining scheme consistent with the physical geometries associated with X- and Ku-band active apertures. A 12-way combiner using stripline serial feed networks in low-temperature cofired ceramic (LTTC) was designed, fabricated, and tested over a...

Zusammenfassung:An effort was made to develop a high-efficiency N-way combining scheme consistent with the physical geometries associated with X- and Ku-band active apertures. A 12-way combiner using stripline serial feed networks in low-temperature cofired ceramic (LTTC) was designed, fabricated, and tested over an 8-14-GHz bandwidth. This combiner was integrated with six dual-channel 1-W MMICs (monolithic microwave integrated circuit) to achieve 10-W peak output power with greater than 86% combining efficiency at center band.< >
