TCR-EHF is an ultra-low profile embedded resistor copper foil specifically engineered for high-frequency applications including 5G mmWave, satellite communications, and defense systems. This advanced thin film embedded resistor technology features very low-profile copper foil architecture that minimizes insertion loss and addresses critical “skin effect” challenges at mmWave frequencies. The precision vacuum metallization process deposits nickel chromium (NiCr) and nickel chromium aluminum silicon (NCAS) alloys with uniform element ratios, delivering superior signal integrity in mmWave pcb substrate designs and phased array pcb materials.

TCR-EHF features an ultra-low profile copper foil design specifically optimized for high-frequency applications:

• Lower insertion loss: Very low-profile architecture minimizes signal losses at mmWave frequencies
• Reduced skin effect: Optimized conductor geometry reduces skin effect losses over entire trace length
• Smoother surface: Enhanced roughness profile for superior etching and signal propagation
• High-frequency optimization: Specifically qualified on PPE/PPO polymer laminates for mmWave performance
• Same resistance range: Maintains 10-100k ohm capability of standard TCR
• Enhanced signal integrity: Critical for 5G base stations, phased array antennas, and satellite systems

While standard TCR excels across many applications, TCR-EHF is the optimal choice when minimizing insertion loss at mmWave frequencies is critical.

As communications networks for 5G, Satcom, Defense, Automotive and other applications move toward mmWave frequencies, smoother, thinner copper foils are essential to achieve the low latency and high capacity these networks demand. At high frequencies, the “skin effect” causes current to flow primarily on the conductor surface. Standard copper foils with rough profiles create:

• Higher insertion losses due to increased effective resistance
• Signal degradation over the length of copper traces
  Reduced bandwidth and network capacity
• Poor signal integrity in flat panel, beamforming, AESA and massive MIMO antenna designs

TCR-EHF’s ultra-low profile design with optimized roughness profile delivers best possible insertion loss characteristics critical for next-generation high-frequency networks.

TCR-EHF embedded resistor copper foil enables manufacturing of resistor values from 10 to 100,000 ohms, matching the full range of standard TCR. The technology features nickel chromium (NiCr) and nickel chromium aluminum silicon (NCAS) alloys deposited via precision vacuum metallization, available in multiple sheet resistivities. This wide range supports diverse high frequency embedded resistor applications from precise impedance matching in phased array antenna termination to signal conditioning circuits in millimeter wave beamforming networks.

TCR-EHF achieves superior high-frequency performance with lower insertion losses through multiple design innovations:

• Very low-profile copper foil architecture: Minimizes skin effect at high frequencies through optimized conductor geometry
• Optimal roughness profile: Ensures precise resistor formation and superior etching quality
• Thin and uniform resistive layer: Provides superior final etch tolerances
• Enhanced signal propagation: Improved circuit performance through reduced surface roughness
• Minimized skin effect losses: Optimized over the entire length of copper traces at high frequencies

These characteristics are critical for best possible insertion loss characteristics in 5g pcb materials and mmwave pcb substrate applications where signal integrity directly impacts network performance.

The skin effect is a phenomenon where alternating current (AC) tends to flow primarily on the surface of a conductor at high frequencies. As frequency increases, current penetration depth decreases, effectively increasing resistance and causing signal losses. This becomes particularly critical at mmWave frequencies (30-300 GHz) used in:

• 5G base station infrastructure
• Millimeter wave communication systems
• Phased array antenna systems
• Satellite communication circuits
• AESA radar systems

TCR-EHF’s ultra-low profile design minimizes skin effect losses by providing a smoother conductor surface, reducing effective resistance and maintaining signal integrity across the entire frequency range.
