These laminates have low loss over high frequencies, making them useful in satellite power supply designs. The RT/duroid 6000 series offers excellent thermal management capabilities.

TC350 Thermal Management Materials

TC350 bonding films provide thermal conductivity and electrical insulation. They can be used to draw heat away from sensitive electronics in the hostile thermal environment of space. TC350 films are useful for attaching power components.

Benefits of Rogers Materials for Satellite Power Systems

Rogers’ circuit materials offer key advantages for managing power in satellite systems:

• Withstand extreme temperatures from -65 to 260°C
• Maintain stable electrical properties through thermal cycling
• High thermal conductivity for heat dissipation
• Tight dielectric constant tolerances for precise circuit design
• Excellent passive intermodulation (PIM) performance
• Enable high frequency operation
• Lightweight
• Easy processing and patterning

By selecting the right Rogers’ material, satellite power systems can operate reliably even under the extreme conditions of space. Materials like the RO4000 series, RT/duroid 6000 laminates, and TC350 films are designed to meet the demanding requirements of satellite power management.

Key Applications of Rogers Materials in Satellite Power Systems

Rogers’ circuit materials serve important functions across satellite power architectures:

Satellite Power Distribution

The RO4000 and RT/duroid 6000 series are ideal laminates for power distribution units that regulate and control voltage to subsystems. Their low loss properties and thermal management capabilities are critical for effective power distribution.

Power Amplifiers and Converters

Power amplifiers and DC-DC converters rely on Rogers’ materials for stable, reliable performance. The RO4000 series’ low passive intermodulation helps minimize distortion in power amplifiers.
