Mini-Circuits’ EP4KA+ is a MMIC 4-way 0° splitter/combiner designed for wideband operation from 10.7 to 31 GHz supporting many applications requiring high performance across a wide frequency range including LTE bands through phased array radars, 5G, 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 technol- ogy, the EP4KA+ not only provides a repeatable performance, but also a high level of ESD protection.
