Marki Microwave, an innovator in the field of RF and microwave components, has introduced its latest 2-18 GHz MMIC 4-Way Wilkinson Power Divider/Power Splitter. The MPD4-0218CSP3 is a small-footprint MMIC 4-way power divider/power splitter, featuring high isolation of 29 dB and low excess insertion loss of 0.8 dB housed in a compact CSP3 chip-scale package.
Designed for next-generation systems where size and performance are critical, the Marki MPD4-0218CSP3 significantly outperforms traditional PCB-based Wilkinson dividers. It has a compact form factor, measuring 3.5 x 3.5 mm that allows for aggressive SWaP (Size, Weight, and Power) optimization, making it ideal for integration in military, aerospace, and advanced commercial platforms.
The MPD4-0218CSP3 Power Divider / Combiner ensures tight amplitude and phase matching, with typical values of 0.16 dB and 2.2° between adjacent ports. Return loss performance is robust, with 22 dB at the common port and 21 dB at the outputs, ensuring minimal signal reflection. It also operates effectively as a power combiner with consistent isolation of 22 dB (adjacent ports) and 29 dB (non-adjacent), and supports seamless modeling through production-measured S5P files.
Electrical performance is supported by a nominal power split of 6 dB, 50 Ω impedance, and zero nominal phase shift. This Power Divider / Combiner from Marki Microwave operates from –55 °C to +100 °C with a 40 mA current requirement and is qualified for rugged environments with an ESD rating of 250–500 V (HBM Class 1A) and MSL 1 moisture tolerance. It can be safely stored between –65 °C and +125 °C, enhancing its reliability in harsh environments.
This makes the MPD4-0218CSP3 a compelling solution for broadband signal distribution and combining in radar systems, electronic warfare (EW), high-speed communications, and test equipment – all applications where accuracy and miniaturization are paramount. With its unmatched blend of bandwidth, compactness, and precision, this MMIC 4-way power splitter stands out as a high-performance building block for advanced RF and microwave system designers.
