A 1-to-4 Wilkinson RF splitter combiner distributes microwave signals from one input to four matched outputs or combines four inputs into one output. The device operates from 17 GHz to 32 GHz with typical excess insertion loss down to −1.7 dB from 22 GHz to 27 GHz. It provides matched output phase and amplitude for low-skew signal distribution in phased-array and microwave systems. The package is a compact 20-ball wafer-level chip-scale package measuring 2.460 mm by 2.460 mm by 0.500 mm. The operating temperature range is −40°C to +85°C, and the Z suffix denotes RoHS compliance.
