4246-52

Overview

The PE4246-52 is a single-pole single-throw (SPST) radio frequency switch manufactured by pSemi. It operates from DC to 5 GHz with a 50 Ohm characteristic impedance. The device features a maximum insertion loss of 1 dB and supports a nominal +3-volt power supply. It is housed in a compact 3x3 mm DFN-6 package, utilizing UltraCMOS technology for low-loss performance and high isolation.

Feature Summary

• UltraCMOS RF-SOI technology enables superior linearity and low insertion loss
• Integrated CMOS control logic allows direct interface with standard digital signals
• Compact 3x3 mm DFN-6 package optimizes board space efficiency

Applications

• Wireless LAN infrastructure
• Mobile handset front-end modules
• RF signal routing in test equipment

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as required by project specifications. Ensure the component source matches the manufacturer's authorized distribution channels to guarantee authenticity and traceability.

Selection Notes

Select this component when a low-loss SPST switch is required up to 5 GHz. Consider the 3x3 mm footprint for space-constrained designs. Evaluate the 1 dB insertion loss and 3V operation against system power and signal integrity requirements.

Part Context

This part belongs to the UltraCMOS family of RF switches. It complements other pSemi devices like the PE4245 series, offering similar performance characteristics but tailored for specific frequency ranges and pin configurations within the broader portfolio of intelligent RF electronics.

Replacement Considerations

PE4246-52/TR is the tape-and-reel variant of the same functional device. Direct substitutes are not explicitly confirmed in public documentation; verify compatibility with alternative SPST switches based on impedance and frequency specs.
