PCAT0404X-9R0CT-CT

Overview

PCAT0404X-9R0CT-CT is a fixed RF attenuator manufactured by Venkel. It provides an attenuation value of 9 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 3 GHz and supports a power rating of 100 mW. It utilizes a convex surface mount package with dimensions corresponding to the 0404 (1010 Metric) size standard.

Feature Summary

• Provides precise 9 dB signal attenuation for RF applications
• Maintains 50 Ohm impedance matching across the operational bandwidth
• Supports operation up to 3 GHz frequency range
• Features a convex surface mount design for reliable PCB integration

Applications

• RF signal conditioning circuits
• Impedance matching networks
• Signal level control in communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific package variant, as Venkel offers both convex and flat configurations for this series. Confirm that the 100 mW power rating aligns with your thermal management requirements. Ensure the 3 GHz frequency limit meets your system's maximum operating speed. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a fixed 9 dB reduction is required in a 50 Ohm system. Consider the 0404 footprint constraints during layout. Evaluate thermal dissipation needs against the 100 mW limit. Compare against variable attenuators if adjustable gain is needed instead of fixed attenuation.

Part Context

This part belongs to Venkel's PCAT series of RF attenuators. The series includes various attenuation values and package types. The 'X' suffix typically denotes the convex package style. This specific model targets high-frequency applications requiring stable attenuation without active components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing footprints before considering alternative manufacturers. Ensure replacement parts match the 50 Ohm impedance and 3 GHz frequency specifications.
