ATV321CR-071DBL

Attenuators Overview

The YAGEO ATV321CR-071DBL is a surface-mount RF attenuator designed for high-frequency signal processing. It features a 50 Ohm impedance and provides an attenuation value of 1dB. The component operates within a frequency range of 0 Hz to 2.5 GHz, supporting applications in microwave circuits. It utilizes a concave 0404 (1010 Metric) package with a power rating of 40mW. The device is constructed using thin-film technology on a ceramic substrate, ensuring stability across the specified operational bandwidth.

Attenuators Feature Summary

• Provides precise 1dB signal attenuation for RF circuitry
• Operates effectively from DC up to 2.5 GHz frequencies
• Utilizes a compact concave 0404 surface-mount footprint
• Maintains 50 Ohm system impedance for standard integration

Attenuators Applications

• RF signal conditioning in communication systems
• Microwave circuit testing and measurement equipment
• Signal level adjustment in wireless transceivers
• Impedance matching networks in high-frequency modules

Attenuators Procurement Notes

Verify the specific suffix 'CR-071DBL' against the manufacturer's official datasheet to confirm the exact attenuation tolerance and termination style. Ensure that the procurement source provides documentation confirming RoHS compliance and lead-free status as stated in public listings. Cross-reference the 0404 package dimensions with PCB layout requirements before ordering to guarantee mechanical fit.

Attenuators Selection Notes

Select this component when a fixed 1dB attenuation is required for signals up to 2.5 GHz. The 40mW power rating dictates suitability for low-power RF paths rather than high-power transmission lines. The concave 0404 package offers a small form factor ideal for dense layouts. Consider thermal management capabilities if operating near the maximum power limit in enclosed environments.

Attenuators Part Context

This part belongs to the ATV321 series of thin-film chip resistors manufactured by YAGEO. These components are specifically engineered for radio frequency applications requiring stable performance at high frequencies. The series utilizes advanced thin-film deposition techniques to achieve tight tolerances and low noise characteristics suitable for precision electronic circuits.

Attenuators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative suppliers by matching the 50 Ohm impedance, 1dB attenuation value, 0404 package size, and 2.5 GHz frequency range specifications.
