FMicirxoweavedPreAcisiotntenuator Die YAT-D-SERIES
50Up to 2W DC to 26.5 GHz
The Big Deal
• Excellent power handling, up to 2W
• Wideband, DC to 26.5 GHz
• Usable to 40 GHz
• Unpackaged die form
Product Overview
YAT-D-series MMIC attenuator dice (RoHS compliant) are fixed value, absorptive attenuators fabricated
using highly repetitive MMIC processing with thin film resistors on Silicon substrates. They contain through-
wafer Cu metallization vias to realize low thermal resistance and very wideband operation. YAT attenuator
dice are available from stock with nominal attenuation values of 0 to 10 dB (in 1 dB steps), and 12, 15, 20,
and 30 dB.
Key Features
Feature
Wideband operation, DC to 26.5 GHz
Usable to 40 GHz
High power handling, up to 2W
Wide range of nominal attenuation values:
• 0 to 10 dB (in 1 dB steps) and 12, 15, 20
and 30 dB
Advantages
YAT-D-series attenuator dice support a wide array of applications including wire-
less cellular, microwave communications, satellite, defense and aerospace, medical
broadband and optical applications. They are also usable in applications up to 40
GHz such as 5G systems (See application note AN-70-019).
Power handling up to 2W makes YAT attenuator dice suitable for a wide range of
system power requirements.
Small increment offerings enable circuit designers to change attenuation values without
motherboard redesign, making the YAT-D-series ideal for adjusting attenuation values
based on test results.
Excellent attenuation flatness
Provides precise, consistent attenuation across the entire frequency band, ideal for broad-
band and multi-band usage.
Unpackaged die
Enables the user to integrate the attenuator die directly into hybrids.
