Chip Attenuators

Chip Attenuators

High Power Handling: Up to 250 W (pulsed/CW).
Broadband Performance: DC–18 GHz.
Temperature-Stable & Temperature-Variable Designs:
- Standard (Temperature-Stable): Uniform RF power reduction across all temperatures.
- Temperature-Variable: Attenuation decreases at elevated temperatures for signal-leveling applications.
Powerfilm™ Technology: Precision thin/thick-film resistors for optimized RF performance.

Power Rating: 250 W (average power, depending on substrate).
Frequency Range: DC–18 GHz.
Attenuation Range: 1–30 dB (customizable).
Attenuation Accuracy: ±0.25 dB (typical).
VSWR: <1.3:1 (typical).
Substrate Materials: BeO (Beryllium Oxide), Aluminum Nitride (AlN), or Alumina Ceramic (thermal/mechanical optimization).
Resistor Technology: Thin/Thick-Film options for power and frequency requirements.
Surface Finishes: Solderable, Silver, or Gold plating for reliable bonding.
Package Sizes: Multiple SMT-compatible dimensions.
