MMIC Surface Mount EP4RKU+ Power Splitter/Combiner 4 Way-0 50 DC to 18 GHz The Big Deal Ultra-wide bandwidth, DC to 18 GHz High Isolation, 20 dB typ. at 9 GHz Small size, 5 x 5 x 1 mm CASE STYLE: DG1677-2 Product Overview 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 alll 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. Key Features Feature Advantages One power splitter can be used in a HF thru, LTE bands, WiMax and WiFi, saving Wideband, DC to 18 GHz component count. Also ideal for wideband applications such as military and instrumen- tation. Excellent Amplitude unbalance, 0.3 dB typ. at 9 GHz Ideal for Applications such as MIMO & phased array radars Excellent phase unbalance, 2 typ. at 9 GHz Tiny footprint saves space in dense layouts while providing low inductance, repeatable Small size, 5 x 5mm QFN package transitions, and excellent thermal contact to the PCB.
