Strategic Analysis

Executive Brief

Comba Telecom is a global leader in wireless solutions, specializing in the R&D and manufacturing of infrastructure for mobile networks (2G through 5G). Their core technical expertise lies in Distributed Antenna Systems (DAS), RF subsystems, and microwave backhaul. As telecommunications move toward higher frequencies (mmWave) and higher power densities, Comba faces significant engineering hurdles in thermal dissipation, signal loss, and component reliability—all of which are primary use cases for 6C’s Diamond Technology.

Strategic Fit & Lead Score

Lead Score: 78/100

Why this Score? Comba's product roadmap is heavily reliant on high-power RF components. The transition to 5G and beyond increases the heat flux in Power Amplifiers (PAs) and complicates signal integrity in microwave subsystems. 6C’s Polycrystalline Diamond (PCD) is the industry's ultimate heat spreader for GaN-based RF devices, and our MPCVD systems could allow Comba to integrate "Diamond-on-GaN" or diamond heat-sinking directly into their high-volume manufacturing lines in Guangzhou.

6C Solutions Proposal

Application Area 6C Solution Technical Value Prop
RF Power Amplifiers (PAs) PCD Heat Spreaders Diamond’s thermal conductivity (>1800 W/mK) is 4-5x higher than Copper. Reduces junction temperatures by 30-50%, extending the lifespan of DAS and repeater power modules.
Microwave Backhaul PCD Microwave Windows Ultra-low dielectric loss (tan δ < 10-4) and high transparency. Enables high-power microwave transmission with minimal signal attenuation or thermal distortion.
5G Massive MIMO Direct Diamond Coating Selective MPCVD coating on RF filter housings or high-frequency substrates to manage extreme heat density in compact, outdoor 5G enclosures without active cooling.
R&D Infrastructure Custom MPCVD Systems Enable Comba’s China/USA R&D centers to develop proprietary "Diamond-on-Device" recipes, moving beyond standard off-the-shelf thermal solutions.
High-Purity Hydrogen 9N Hydrogen Generators Support Comba's existing semiconductor-grade testing and manufacturing facilities with ultra-pure (99.9999999%) H2 for clean processing environments.

Engagement Hooks

  • Technical Question: "As Comba scales its 5G Massive MIMO and microwave backhaul solutions, are you finding that traditional copper or AlN (Aluminum Nitride) heat spreaders are forcing a trade-off between power output and the MTBF (Mean Time Between Failure) of your RF power modules?"
  • Value Statement: "6C can help Comba break the thermal ceiling of 5G infrastructure by integrating MPCVD diamond components that offer 2000 W/mK conductivity, effectively doubling the power density of your existing wireless enhancement products."
