Precision RF & Microwave Components for Commercial Systems
MCLI designs and manufactures RF microwave components for commercial systems that demand signal integrity, reliability, and repeatable performance across wireless infrastructure, satellite communications, industrial platforms, and test equipment.
Commercial RF Systems Need Components That Perform Under Real Conditions
Commercial RF and microwave systems operate in environments where signal density is increasing, frequency allocations are tightening, and performance tolerances leave little room for error. Whether the application is a 5G base station, a SATCOM ground terminal, or an industrial IoT gateway, the RF and microwave components in your signal chain determine how well your system handles those conditions.
Power dividers that drift under thermal load. Attenuators that introduce noise at the wrong frequency. Couplers that cannot maintain flat coupling across your operating band. These are the problems that show up in the field, not on the datasheet. Choosing the right RF microwave components for commercial systems is not just a procurement decision. It is an engineering one.
MCLI designs and manufactures passive and active RF-microwave components for commercial systems that need to work the first time and keep working. Over 40 years of RF engineering, 100% USA manufacturing, and a 50,000 sq. ft. production facility with in-house testing give us control over every step from design through delivery.
The Commercial RF Challenge
Commercial RF systems are getting harder to build well. Here is what engineers are running into across wireless, satellite, industrial, and test applications:
- Higher frequency demands. 5G mmWave, Ka-band satellite, and next-generation radar are pushing systems into frequency ranges where component performance falls off faster. The FCC continues to allocate mid-band and high-band spectrum for commercial 5G deployment, with auctions covering the 3.5 GHz, 3.7 GHz, and 24–47 GHz bands. As commercial systems move into these bands, insertion loss, VSWR, and isolation specs that were acceptable at L-band become problems at 18 GHz and above.
- Dense signal environments. More transmitters in less spectrum means more interference. Power dividers, couplers, and filters have to maintain isolation and rejection performance in crowded RF environments where adjacent-channel signals are close and strong.
- Tight performance tolerances. System-level specifications leave less margin at the component level. An extra 0.3 dB of insertion loss in a power divider might not matter in isolation, but it compounds across a multi-stage signal chain.
- Integration across multi-component systems. Commercial platforms combine dozens of passive and active components. Impedance mismatches between stages degrade system performance. Components need to work together, not just meet individual spec sheets.
How MCLI Solves It
MCLI addresses these challenges at the component level with precision-engineered RF and microwave products built for real commercial operating conditions. Our RF solutions for commercial systems start with the fundamentals: low loss, high isolation, consistent impedance, and broadband frequency coverage.
- Broadband frequency coverage. 5GPower dividers, couplers, hybrids, and attenuators covering DC to 70 GHz. Broadband models reduce the number of components in your system and simplify multi-band designs.
- Low insertion loss and high isolation. Stripline, microstrip, and lumped element construction methods are selected for each application to minimize signal degradation and maximize port-to-port isolation.
- Consistent VSWR across the operating band. Tight impedance control at every port reduces reflections and keeps your signal chain matched from source to load.
- Custom designs produced in-house. Hundreds of custom-designed components are engineered and manufactured each year. Modified frequency ranges, coupling values, connector configurations, and mechanical packages are available without long lead times.
Result: More reliable commercial systems with lower noise, better signal integrity, and fewer integration surprises.
Commercial Applications We Support
MCLI commercial RF components are specified across four primary application areas. Each demands a different combination of frequency coverage, power handling, environmental tolerance, and delivery speed.
Wireless Infrastructure
Base stations, small cells, repeaters, and distributed antenna systems (DAS) rely on power dividers, combiners, and attenuators that maintain performance across wide frequency ranges. MCLI supplies in-stock and custom models for cellular, 5G, and point-to-point wireless builds where insertion loss and amplitude balance directly affect coverage and capacity.
See our full lineup on our Power Dividers and Combiners page.
Satellite and Communications
SATCOM ground terminals, transponder chains, and uplink/downlink subsystems depend on RF components for satellite communications that hold specification across temperature swings, humidity, and continuous operation. Directional couplers for power monitoring, isolators for amplifier protection, and hybrids for signal combining are all standard requirements in satellite ground infrastructure.
See available models on our Directional Couplers page.
See available models on our Isolators and Circulators page.
Industrial and IoT Systems
Connected industrial platforms, SCADA telemetry, and IoT gateways use RF components that need to perform reliably in electrically noisy environments. Attenuators for signal level management, bias tees for powering remote devices, and switches for routing between sensors are common in these systems.
See specifications on our Variable and Fixed Attenuators page.
See specifications on our Bias Tees page.
Test and Measurement Equipment
Calibration, validation, and diagnostic systems require components with tight tolerances and repeatable performance. Power dividers for signal distribution, couplers for non-invasive power sampling, phase shifters for beam characterization, and terminations for impedance matching are used throughout commercial test setups.
See details on our Phase Shifters page.

Why Engineers Choose MCLI for Commercial RF Components
MCLI has designed and manufactured precision RF-microwave components for over 40 years, all from a 50,000 sq. ft. facility in Saint Petersburg, FL. Every component is produced and tested in-house under ISO 9001:2015 quality controls, which means we maintain full visibility over materials, assembly, and final performance verification. That level of control matters when your commercial system has a noise budget measured in tenths of a dB.
Our product catalog includes over 1,700 power divider models alone, with coverage from DC to 70 GHz and power handling up to 10,000 W. Many standard configurations ship the same day they are ordered. For non-standard requirements, our engineering team produces hundreds of custom-designed components each year with modified frequency ranges, connector types, coupling values, and mechanical packages.
All manufacturing happens in the USA. Environmental and quality testing follows MIL-STD-202 standards, including thermal shock from -55 to +85°C, vibration testing at 20 G’s, and humidity exposure at 90% RH. RoHS compliance documentation is available for every product line. For commercial system builders who need components that perform to specification under real operating conditions, that is the foundation we start from.
