HIGH-SPEED INTERCONNECTS FOR RADAR AND ELECTRONIC WARFARE SYSTEMS

In high-frequency radar and electronic warfare (EW) systems, signal integrity is not just a performance metric, it’s mission-critical. As modern defense platforms increasingly rely on high-bandwidth RF and microwave technologies for detection, jamming, surveillance, and countermeasures, the need for rugged, low-loss interconnects becomes a foundational design challenge. Meritec’s advanced high-speed cable assemblies and EW interconnect solutions offer the reliability and performance required in the harshest electromagnetic environments.


From airborne radar systems to ground-based electronic countermeasures, signal chain reliability is essential to real-time data transmission and system response. This blog explores how high-speed interconnects support radar and EW systems, what design factors matter most, and how Meritec solutions address key application requirements across the defense spectrum.

The Evolving Demands of Radar and EW Systems

Electronic warfare and radar systems operate at the intersection of speed, power, and precision. Radar systems depend on high-frequency signal propagation and rapid data processing to detect, identify, and track targets. EW systems, including electronic attack (EA), protection (EP), and support (ES), require fast-reacting, highly secure transmission paths for jamming, spoofing, or intercepting threats.


These applications place several demands on interconnect technology:


  • High-speed signal integrity across long runs
  • RF shielding for EMI suppression
  • Durability under vibration, shock, and extreme temperatures
  • Secure mating to prevent disconnection during operations
  • Low reflection and consistent impedance in RF links


With growing interest in spectrum dominance and multi-domain operations, radar and EW systems are becoming more compact, mobile, and integrated into platforms like drones, ships, satellites, and tactical ground vehicles. Interconnects must now deliver lab-grade performance in field-ready packaging.

Key Design Priorities for High-Speed Interconnects in EW/Radar  

1. Frequency Support and Bandwidth

Radar and EW systems often operate in GHz frequencies, with systems ranging from L-band to Ka-band depending on the application. Connectors and cable assemblies must support high data rates and minimal attenuation across wide frequency bands to preserve signal clarity and fidelity.

2. Shielding and Crosstalk Mitigation

Interconnects in EW systems are often adjacent to high-powered RF sources. Shielding solutions such as braid-over-foil designs, triaxial configurations, or EMI-optimized overmolding can dramatically reduce radiated emissions and signal leakage. Maintaining signal isolation is essential in multi-channel systems.

3. Mechanical Robustness

Field-deployed radar and EW systems are exposed to mechanical shock, repeated movement, and harsh conditions. Interconnect solutions must incorporate strain reliefs, locking mechanisms, ruggedized housings, and environmental sealing to MIL-spec standards.

4. Impedance Control and Low Return Loss

At GHz frequencies, even minor mismatches in impedance can cause signal reflections and reduce system sensitivity. Controlled-impedance cable assemblies with precision-matched connectors preserve waveform integrity from source to receiver.

5. SWaP Optimization

Space, weight, and power (SWaP) constraints are a constant in aerospace and defense. Lightweight, flexible cable assemblies that provide high-density signal paths in minimal footprints are increasingly valuable in radar pods, EW payloads, and unmanned systems.
