Mini-Circuits’ EP4RKU+ is a MMIC 4-way 0° splitter/combiner designed for wideband operation from DC to 18 GHz supporting many applications requiring high performance across a wide frequency range including all the LTE bands through WiMax and WiFi, as well as instrumentation and more. This model provides good isolation, and low phase and amplitude unbalance in a small 5 x 5mm QFN package. Manufactured using GaAs IPD tech- nology, the EP4RKU+ not only provides a repeatable performance, but also a high level of ESD protection.
