3501-52

Overview

The pSemi 3501-52 is a general-purpose RF IC prescaler designed for high-frequency signal processing applications. Operating within a frequency range of 400MHz to 3.5GHz, this component functions as a divide-by-2 prescaler, effectively halving the input signal frequency. Manufactured using UltraCMOS technology, it is housed in an 8-TSSOP surface-mount package with a width of 4.40mm. The device is classified under RF miscellaneous ICs and modules, providing a compact solution for frequency division tasks in radio frequency systems.

Feature Summary

• UltraCMOS technology implementation for efficient RF signal processing
• General-purpose divide-by-2 prescaler functionality
• Surface-mount 8-TSSOP packaging for automated assembly

Applications

• RF signal frequency division in communication systems
• High-frequency circuit design requiring prescaling
• Radio frequency integrated circuit modules

Procurement Notes

Verify component status carefully as the 3501-52 is officially listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers, noting that new production may be limited. Ensure compatibility with existing designs before sourcing, as end-of-life components often require careful lifecycle management and potential redesign planning for long-term projects.

Selection Notes

Select this component when a divide-by-2 prescaler is required for frequencies between 400MHz and 3.5GHz. The 8-TSSOP package suits space-constrained surface-mount designs. Consider the UltraCMOS process for specific performance characteristics. Due to its obsolete status, evaluate alternative solutions if long-term supply stability is critical for the application.

Part Context

The 3501-52 belongs to the UltraCMOS series from pSemi, targeting RF miscellaneous IC applications. It serves as a specialized prescaler within the broader portfolio of radio frequency components. The part number 3501-52 is distinct from aliases like PE3501, representing a specific hardware configuration optimized for divide-by-2 operations in the specified frequency band.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must identify functional equivalents independently based on electrical specifications such as frequency range, division ratio, and package type.
