About Marki Microwave

With over 30 years of innovation, Marki is recognized for delivering broadband, high-linearity, high-reliability solutions that help customers accelerate development, reduce design complexity, and improve RF system performance.

Marki Microwave products are widely used across space, aerospace, defense, satcom, test and measurement, quantum, and advanced communications applications where performance and integration flexibility are critical.

Performance

By combining time-proven fabrication and assembly techniques with advanced RF design methodologies, these technologies push the boundaries of broadband and mmWave performance. Innovations such as the T3 Mixer® family, high-isolation power combiners, and an expanding portfolio of MMIC devices help engineers achieve outstanding linearity, bandwidth, and signal integrity in complex high-frequency signal chains.

High-Frequency Expertise

Marki Microwave specialises in high-frequency RF and microwave components designed for mmWave and sub-THz applications, where wider contiguous bandwidths support high-throughput communications and shorter wavelengths enable high-resolution radar and imaging systems.

To achieve this level of performance, Marki uses advanced 3D electromagnetic simulation and modelling across the full product environment. Alongside MMIC die solutions, a range of different form factors optimized for high frequency operation.

Advanced Packaging

As RF systems become increasingly complex, packaging plays a critical role in overall system performance. Marki simplifies integration with engineered, easy-to-use packaging solutions that ensure optimal board-level performance and signal integrity.

From Chip Scale Packaging (CSP), delivering performance up to 90 GHz in compact surface-mount formats, to multi-octave M-Package designs enabling DC to 120 GHz operation in connectorized solutions, these advanced packaging solutions help engineers accelerate design cycles, reduce integration complexity, and achieve high-performance RF system architectures, while continuing to lead in packaging innovation.

Marki Microwave, LLC Product Range

Mixers & Frequency Conversion

Industry-leading mixer technology, offering a broad range of passive mixers, active mixers, I/Q mixers, image reject mixers, single sideband mixers, and frequency converters to 130GHz. These products are designed to provide excellent conversion loss, high isolation, wide bandwidth, and exceptional linearity, making them ideal for up/down conversion in demanding RF architectures.

RF & mmWave Amplifiers

Their amplifier portfolio includes Low Noise Amplifiers (LNAs), gain blocks, distributed amplifiers, and driver amplifiers, developed to deliver low noise figure, high gain, excellent flatness, and strong linearity across broad frequency ranges. These are well suited for receiver front ends, transmit chains, radar modules, satcom payloads, and test systems.

Power Dividers, Combiners & Couplers

Power dividers, combiners, directional couplers, and hybrid couplers designed to support efficient signal distribution, combining, and monitoring across frequencies up to 110 GHz.

Switches, Limiters & Protection / Routing Components & Conversion

Switches, limiters, DC blocks, bias-tees, diplexers, baluns, inverters and isolators, giving engineers access to a more complete set of RF building blocks for system design. This makes Marki valuable not just for single-function components, but for building out a broader RF signal chain with compatible high-frequency solutions.

Filters, Equalizers & Signal Conditioning

A major part of Marki’s product range is dedicated to signal conditioning, including fixed filters, configurable filters, equalizers, attenuators, level set attenuators, terminations, and related passive RF components. These products help engineers control gain flatness, unwanted harmonics, out-of-band noise, signal shaping, and overall system fidelity. Marki has also expanded its filter offering with high-performance designs and digital design tools aimed at reducing RF design iteration time.

Frequency Multipliers & Signal Generation Components

Frequency multipliers and NLTL comb generators, helping engineers extend LO and signal generation architectures into higher microwave and mmWave frequency bands.
