4239-52

Overview

The pSemi 4239-52 is a general-purpose SPDT RF switch operating from 0Hz to 3GHz. It utilizes UltraCMOS technology and features a reflective topology with 50-ohm impedance. The device is housed in an SC-70-6 package (also identified as 6-TSSOP, SC-88, or SOT-363). Key electrical specifications include a P1dB of 27dBm and an operating temperature range of -40°C to 85°C. This component is currently classified as obsolete.

Feature Summary

Reflective single-pole double-throw (SPDT) topology for signal routing
UltraCMOS technology enabling broadband operation from DC to 3GHz
Compact SC-70-6 surface-mount packaging

Applications

General-purpose microwave and RF signal switching
Test and measurement equipment requiring broadband isolation
Telecommunications infrastructure components

Procurement Notes

Verify availability status carefully as the 4239-52 is listed as obsolete by multiple distributors. Confirm final assembly dates and lot codes if sourcing from remaining stock. Ensure compatibility with existing PCB footprints designated for SC-70-6 packages. Cross-reference pinouts with official datasheets before integration into new designs.

Selection Notes

Select this component only for legacy system maintenance or specific design reuse where the obsolete status is acceptable. Evaluate alternative active parts if new production is required. Consider the 3GHz frequency limit and 27dBm power handling when matching application requirements. Verify that the reflective nature aligns with system VSWR constraints.

Part Context

This part belongs to the UltraCMOS series from pSemi, designed for high-performance RF switching applications. The 4239-52 variant specifically targets general-purpose markets requiring compact form factors. It represents a mature product line now transitioning out of active manufacturing cycles.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Consult manufacturer documentation for current recommended replacements for obsolete UltraCMOS devices.
