Model TCA-N05
Attenuator, Chip
Frequency Range: DC to 12 GHz, Power: 2 Watts
Features
• Reduced Attenuation at Elevated Temperature
• Linear Resistive Design
• Broadband Operation
N05 series of temperature variable attenuators are designed to compensate reduction of gain by 0.5dB/dB for
a temperature increase from 25°C to 125°C without requiring a bias or control voltage. TCA chip attenuators
are manufactured using thick film resistor elements on an alumina ceramic substrate. Blank backside TCA
chips are designed for flip-chip mount applications and available in various attenuation values and terminal
finish options.
