At Marki Microwave our goal is to invent technologies to empower the RF and microwave industry to design faster, simplify production, eliminate complexity, and shatter performance barriers.

We achieve this goal through intensive research, product development, and advanced and carefully controlled production. We have a multi-decade legacy designing high performance microwave components, demonstrating technical leadership through collaboration with thousands of customers. Our extensive knowledge base is enhanced with state-of-the-art test and measurement equipment (capable of measurements from DC-110 GHz). Designs are validated using both the most sophisticated CAD and simulation software available and proprietary design software. All assembly and test is performed under the supervision of the design engineer at the same facility. Our assembly capabilities include precision leaded and lead free solder and wire bonding for gold/thin film assembly. We maintain close relationships with our key suppliers, who are all local to our manufacturing facility.

These capabilities lead to a portfolio of high performance components including broadband, low conversion loss, and highly linear mixers, high directivity, low return loss couplers and directional bridges, well balanced power dividers and hybrid couplers, and many other quality products. A comprehensive collection is listed in the menu above. For most of our products we can provide short lead times and extensive design support. In addition we can meet custom specifications if they are required for most of our catalog products. Please take the time to review our technical library, which is constantly expanding, and in particular our mixer basics primer.

  • MMH-35120H is a GaAs MMIC balanced harmonic mixer that features excellent conversion loss, superior isolations, and spurious performance across an incredibly broad bandwidth utilizing the 3rd harmonic of the LO.

  • The ADM-8007PSM is a high-linearity, high gain, low noise distributed amplifier capable of providing +23 dBm output power up to 38 GHz. 

  • The C10-0667 stripline directional couplers use proprietary circuit design to offer higher directivity than competing stripline couplers across a broad bandwidth. 

  • The MM1A-0832HPSM is a versatile, robust, and broadband double-balanced mixer with an integrated broadband LO driver amplifier that is ideal for wide bandwidths and operation at mmWave frequencies.
