RF Sub-systems
RF Sub-systems for Mission-Critical Communication, Radar, Navigation and Defense Platforms
RF Sub-systems represent the heart of modern high-performance communication and sensing infrastructures. They integrate active and passive RF building blocks—amplifiers, filters, mixers, combiners and electronic control —into complete, fully engineered modules capable of delivering reliable and stable performance in mission-critical environments.
MT design, manufacture, and validate advanced RF Sub-systems used in Air Traffic Control, Land & Naval Communications, Public Safety infrastructures, Cellular & Wireless networks, and specialized defense applications. MT sub-systems combine engineering innovation with rugged, field-proven reliability to ensure consistent operation even under extreme conditions.
What Are RF Sub-systems?
An RF sub-system is a high level integrated assembly combining different devices modules inside a complete rack, to perform specific functions within different commnunications system, as for example : Defence, ATC, Land & Naval, Public Safety , Sea Guard networks.
Main examples :
• 5KW & 10KW RF power in HF band modular amplifiers combined to single antenna, monitored with protocol to Customers’ radio exciters
• Multi-channel system combining into one single antenna all channels remotely tunable via protocol to Customers’ radio exciters
• High power complete base station in HF band for Sea Guard safety networks
Digital Control and Telemetry
- Remote monitoring
- Power management
- Temperature control
- Fault diagnostics
- Alarm signaling
Applications and Markets
RF Sub-systems play a key role in:
Air Traffic Control (ATC)
- VHF/UHF communication towers
- Secondary Surveillance Radar (SSR)
- Navigation and control systems
They must deliver very high selectivity to allow frequency channels separation with high spectral purity, stable operation, and extremely low downtime.
Land & Naval Communications
Naval vessels and land-based tactical systems for reliable long-range communication, in harsh electromagnetic and environmental conditions.
RF Sub-systems must comply with:
- MIL-STD environmental specifications
- High-power RF exposure
- Security and electromagnetic compatibility
Public Safety / Emergency Networks
As for examples, Sub-systems ensure continuous operation of:
- TETRA infrastructure
- DMR (Digital Mobile Radio), SAR ( Search and Rescue), LMR ( Land Mobile Radio), P25 ( APCO-25) project
- Wide-area repeater networks
- Redundant communication paths
Coast Guard rescue & security
HF complete high power base stations for Coast Guard communication systems.
