PE43614A-X

Overview

The PE43614A-X is an UltraCMOS RF digital step attenuator from pSemi, operating within a frequency range of 9 kHz to 45 GHz. It features a 6-bit resolution with a minimum attenuation step size of 0.5 dB, providing a total attenuation control range of 31.5 dB. The device is designed for high linearity and outstanding attenuation accuracy with low insertion loss. It utilizes a 24-pin WFLGA package and supports both serial addressable and parallel digital control interfaces.

Feature Summary

• Ultra-wideband operation extending up to 45 GHz
• Integrated digital control interface supporting serial and parallel modes
• High linearity and precise attenuation accuracy

Applications

• Test and measurement equipment requiring wideband signal attenuation
• Wireless communication systems needing precise gain control
• Radar and electronic warfare applications

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm tape-and-reel packaging configuration. Confirm that the 24-pin WFLGA footprint matches your PCB design constraints. Ensure compatibility with the required digital control logic levels before integration into the system architecture.

Selection Notes

Select this component when ultra-wideband performance up to 45 GHz is required. The 6-bit resolution offers fine granularity suitable for precision calibration tasks. Consider the 24-pin LGA package size relative to available board space. Verify that the system can support the necessary serial or parallel control signals for optimal operation.

Part Context

This part belongs to the pSemi UltraCMOS family of RF digital step attenuators. These devices leverage advanced CMOS technology to provide compact solutions for RF signal management. The PE4361x series is distinguished by its ability to operate at significantly higher frequencies compared to standard silicon-based attenuators, making it suitable for modern high-frequency wireless standards.

Replacement Considerations

The PE43610A-X serves as a lower-frequency alternative within the same product family, covering 9 kHz to 13 GHz. Both parts share similar control interfaces and package types but differ in maximum frequency specifications. Ensure the application does not require the extended bandwidth provided by the PE43614A-X before substituting.
