PE42820B-X

RF Switches Overview

The PE42820B-X is a high-power reflective SPDT RF switch utilizing pSemi's HaRP technology. It operates within a frequency range of 30 MHz to 2.7 GHz and supports a supply voltage of 2.3V to 5.5V. Key electrical parameters include an insertion loss of 0.7 dB, typical off-isolation of 24 dB, and an input third-order intercept point (IIP3) of 81 dBm. The device is housed in a 32-lead 5x5 mm QFN package with exposed pads, designed for surface mount installation across a temperature range of -40°C to +85°C.

RF Switches Procurement Notes

Verify the specific suffix 'B-X' against the manufacturer datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with existing PCB footprints, as this component utilizes a 32-QFN package. Confirm that the required supply voltage range aligns with system power rails before finalizing procurement orders.

RF Switches Selection Notes

Select this component when high linearity and power handling are critical for SPDT switching tasks up to 2.7 GHz. It serves as a direct pin-compatible replacement for the PE42510A, offering extended frequency and voltage ranges. Consider the reflective topology implications on circuit matching networks compared to absorptive alternatives.

RF Switches Part Context

This part belongs to the UltraCMOS and HaRP product families from pSemi, integrating RF, analog, and digital functions on a single die. It represents an evolution in CMOS-based RF switching solutions, providing enhanced performance metrics over earlier generations while maintaining standard form factors for easy integration into modern communication hardware designs.

RF Switches Replacement Considerations

The PE42820B-X is documented as a pin-compatible upgraded version of the PE42510A. Designers replacing older switches should verify that the wider supply voltage range and extended frequency capabilities meet the new system requirements without requiring schematic modifications.
