Advantages of a Low Loss Capacitor:

• Increased power output and higher efficiency from RF power amplifiers
• Reduced amount of heat generated through ultra-low ESR / High-Q
• Signal to noise ratio and overall noise temperature can be improved by lower losses
• Lower in-band insertion loss (S21) when used in filter networks
• Lower resistivity through the heat generation plane to transfer heat allowing higher power dissipation
