4237-52

Overview

The pSemi PE4237-52 is an UltraCMOS SPDT RF switch designed for applications from DC to 4 GHz. It features a low insertion loss of 0.45 dB and a minimum IIP3 of 50 dBm at 50 Ohms impedance. The device integrates on-board CMOS control logic for single-line operation. Manufactured in a compact 6DFN surface-mount package, it supports broad frequency ranges suitable for wireless infrastructure.

Feature Summary

• Integrates on-board CMOS control logic for simplified single-line interface
• Utilizes UltraCMOS technology for high linearity and low power consumption
• Designed as a reflective switch for robust RF signal routing

Applications

• RF and wireless communication systems
• Base station antenna switching
• Test and measurement equipment

Procurement Notes

Verify the specific ordering code suffix (e.g., -52) against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free requirements with the supplier prior to purchase. Cross-reference the part number with official pSemi documentation to avoid confusion with similar series components.

Selection Notes

Select this component when a single-pole double-throw configuration is required up to 4 GHz. The integrated control logic eliminates external driver needs, reducing board space. Ensure the application demands high IP3 performance and low insertion loss within the specified frequency range.

Part Context

The PE4237 series represents Peregrine Semiconductor's UltraCMOS technology, combining MEMS-like performance with CMOS manufacturability. This specific model is part of a broader family including variants like PE4237-00 and PE4237-99, differentiated primarily by packaging or testing standards rather than core electrical function.

Replacement Considerations

The PE4237-00 variant is listed as obsolete. Verify compatibility with alternative SPDT switches from the same manufacturer or other vendors offering comparable 4 GHz UltraCMOS specifications.
