Mini-Circuits Florida is a major manufacturing and engineering facility of Mini-Circuits, a global supplier of RF, microwave, and signal-processing components and systems. The Florida operation is located in Hialeah, Florida, and has played an important role in Mini-Circuits’ U.S. manufacturing network for decades. The company’s global locations page identifies Hialeah as a key manufacturing location, with capabilities spanning warehousing and shipping, testing, manufacturing automation, assembly, design engineering, and quality assurance.

Mini-Circuits develops and manufactures a broad range of RF and microwave products used in wireless communications, test and measurement, aerospace and defense, satellite communications, instrumentation, and other high-frequency electronic applications. Its product portfolio includes RF amplifiers, attenuators, filters, mixers, frequency multipliers, oscillators, splitters, combiners, couplers, switches, transformers, connectors, cables, and RF modules. The company also provides technical resources and engineering support for customers selecting components for specific frequency and performance requirements.

The Hialeah facility has expanded considerably over time. Mini-Circuits states that the Florida location was established in 1976 and has operated from its current location since 1997. Recent investments have added surface-mount technology (SMT), incoming and final inspection, production testing, manufacturing process engineering, warehouse operations, PCB singulation, and harness manufacturing. In 2023, Mini-Circuits announced a new SMT department equipped with pick-and-place equipment, a reflow oven, X-ray inspection, and other production technology.

More recently, the Florida facility has expanded its testing capabilities. Mini-Circuits reported in 2025 that the Hialeah operation was testing more than 80% of the products assembled there, supporting a more complete build-and-test workflow at the facility.

Mini-Circuits Florida is therefore an important location for RF component manufacturing, electronic assembly, testing, engineering, and quality assurance, supporting Mini-Circuits’ broader global RF and microwave technology business.
