Lowers Junction Temperatures for Improved Power Amplifier Reliability
• Power density continues to increase
• Packaging getting smaller and hotter
• Higher temperatures reduce component reliability
• Tower mounted and outdoor electronics increase environmental exposure while requiring higher reliability
• Complex waveforms decrease amplifier efficiency, more energy lost to heat
Dielectric Constant Stability Across Wide Temperatures
• Helps power amplifier and antenna designers minimize dead bandwidth, which is lost to dielectric constant drift as operating temperature changes
• For antenna designs, a significant shift in resonance frequency and bandwidth roll off at specific frequencies, results in lower gain performance
• Thermal stability feature is critical to phase sensitive devices such as impedance network transformers utilized for matching networks of power amplifiers
Arlon is in the midst of launching TC600, a 6.15 dielectric constant material that doubles the thermal conductivity of existing materials in the 6 dielectric constant market while achieving very low loss (0.0022 at 10 GHz via IPC TM-650 2.5.5.5 Test). This material also has excellent CTE and thermal-electric stability, the key to improved performance.
