4246-51

Overview

The PE4246-51 is a single-pole single-throw (SPST) RF switch manufactured by pSemi. It operates from 1 MHz to 5 GHz with a characteristic impedance of 50 Ω. The device features a maximum insertion loss of 1.8 dB and a minimum input third-order intercept point (IIP3) of 50 dBm. It utilizes CMOS control logic and functions within an operating temperature range of -40°C to 85°C. The component is housed in a compact 6-pin DFN package measuring 3x3 mm.

Feature Summary

• Single-pole single-throw configuration for signal routing
• Integrated CMOS control logic for low-voltage operation
• High linearity performance with 50 dBm IIP3
• Compact surface-mount DFN packaging

Applications

• RF signal switching in wireless communication systems
• Test and measurement equipment signal paths
• Mobile device front-end modules
• Base station antenna switching networks

Procurement Notes

Verify the specific suffix '-51' against official pSemi documentation to confirm pinout and electrical specifications, as suffixes often denote tape-and-reel packaging or specific testing criteria. Confirm current availability status, as this part may be discontinued or obsolete according to distributor listings. Ensure compatibility with existing PCB footprint and thermal management requirements during integration.

Selection Notes

Select this component when a high-linearity SPST switch is required for frequencies up to 5 GHz. The 50 dBm IIP3 makes it suitable for applications demanding high dynamic range. Consider the 3x3 mm DFN package size for space-constrained designs. Verify that the system voltage aligns with the CMOS control interface requirements before finalizing the design.
