Co-Packaging Technique Improves Mixer Performance While Reducing Design Time and Footprint
Milan – Sept. 27, 2022 – European Microwave Week – Marki Microwave®, innovator in the radio frequency and microwave industry for over 30 years, today announced the expansion of its millimeter wave (mmWave) portfolio with a series of leading-edge mixers featuring integrated local oscillator (LO) drivers. Ideal for space constrained applications requiring wide bandwidths and operation at mmWave frequencies, the integrated drive mixers reduce size, weight, power and cost (SWaP-C) while simplifying overall integration of the LO path for ease of use and optimized performance.
“For customers needing to realize the best performance in a small footprint with reduced design effort, our latest integrated drive mixers are game changers,” said Duncan Pilgrim, vice president of sales and marketing at Marki Microwave. “The designs deliver high performance across a wide bandwidth with reduced drive requirements, promising ease of use in a traditionally complex design space.”
The MM1A-0832HPSM, MM1A-1040HPSM and MM1A-1855HPSM are versatile, broadband double balanced mixers featuring an integrated LO driver amplifier, which allows for operation with LO powers as low as -6 dBm. Unlike traditional industry solutions using discrete packages, which often suffer from subpar performance, Marki Microwave’s co-packaging utilizes optimal die technology for the amplifier and mixer functions. The new technique eliminates the need for a separate amplifier and mixer interface, minimizing design costs without sacrificing performance across the operating bandwidth. The new integrated drive mixers’ exceptional conversion loss and linearity combined with their compact footprint make the parts an ideal solution for high performance test and measurement, aerospace and defense, telecom infrastructure and satellite designs.
The MM1A-0832HPSM, MM1A-1040HPSM and MM1A-1855HPSM will be available in October in 3 x 4.6 mm QFN packages. Specifications subject to change without notice. For samples and sales information, contact [email protected].

Featuring Better Than Five Degrees of Phase Balance, the Balun Delivers Unmatched Performance for Next-Generation Data Converters
Denver, CO – June 21, 2022 – International Microwave Symposium – Marki Microwave, innovator in the radio frequency and microwave industry for over 30 years, today introduced the BAL-0032SSG, a surface mount broadband balun, hand-tuned for optimal phase and amplitude balance over an industry leading 10 MHz to 32 GHz. As the microwave market’s first surface mount balun to enable 32 GHz of instantaneous bandwidth with better than five degrees of phase balance, the BAL-0032SSG supports high sample rate data converters for wideband receive architectures, multiband RADAR, digital beamformers and direct conversion receivers.
“An increasing number of systems are transitioning over to direct conversion architectures, where the speed of the data converters defines the maximum frequency of operation,” said Christopher Marki, CEO of Marki Microwave. “For customers eager to drive higher performance, the BAL-0032SSG enables an unprecedented frequency range that supports 32 GHz of bandwidth, making it ideally suited to the next generation of high-speed data converters.”
Leveraging the technology of the BAL-0020SLG, Marki Microwave’s 10 MHz to 20 GHz surface mount broadband balun, the BAL-0032SSG is a 1:2 transformation line transformer balun that can maintain phase balance of better than five degrees across the entire band and amplitude balance of better than 0.4 dB, which causes minimal effect on signal integrity. In addition, the balun allows processing of the complete band, optimizing applications that require high instantaneous bandwidth (iBW), which enables electronic warfare receivers to cover multiple frequency bands and multi-band radar solutions. Designed in an ultra-compact 5.0 x 8.5 mm surface mount package, the BAL-0032SSG is available now. Specifications subject to change without notice.

Co-Development of Die and Innovative M-Package Enables Exceptional Mixer Performance
Denver, CO – June 21, 2022 – International Microwave Symposium – Marki Microwave, innovator in the radio frequency and microwave industry for over 30 years, today introduced a family of broad bandwidth mmWave mixers, offered in die form or in the company’s innovative M-package design, which allows for DC to 100 GHz+ operation for any two, three or four port MMIC device. The unique packaging approach delivers optimized performance and makes the mixers a mechanically reliable solution.
“There is an ever-present demand for multi-octave higher frequency operation, however the RF and microwave industry has been challenged in creating designs at these frequencies while utilizing the wider bandwidths available,” said Christopher Marki, CEO of Marki Microwave. “Designing the die is only a piece of the puzzle. To maintain the die level performance, the packaging at these high frequencies is an integral part of the design process. This co-development of die and package is an area where Marki Microwave excels.”
As Marki Microwave’s newest product category, the mmWave mixers support an incredibly broad bandwidth with frequencies up to 130 GHz, while delivering excellent conversion loss, superior isolation and high linearity. Additionally, the products compete favorably against existing wave guide solutions. These mixers are ideally suited for ultra-broadband receivers, test and measurement equipment, automotive radar and test receivers for 5G and upcoming 6G standards. Their ultra-broadband operation can simplify customers’ designs and procurement overhead by reducing the number of variants required.
Sampling for the mmWave mixers is estimated to begin in July. The MM1-30100L, MMIQ-40100L and MMIQ-40100H are available in bare die or a connectorized M-package, while the MM1-35130H is currently offered in die form only.
