PE42452A-Z

RF Switches Overview

The PE42452A-Z is an SP5T RF switch IC from pSemi’s UltraCMOS series, designed for high-isolation applications. It operates within a frequency range of 450 MHz to 4 GHz with a 50-ohm impedance. Key electrical parameters include a typical insertion loss of 1.6 dB and a typical off-state isolation of 42 dB at 4 GHz. The device supports a wide operating temperature range from -40°C to +105°C and is available in a 24-pin QFN package.

RF Switches Feature Summary

• Absorptive topology provides high isolation by terminating reflected signals, reducing intermodulation distortion.
• SP5T configuration allows selection among five distinct output ports from a single input.
• UltraCMOS technology enables robust performance across extended industrial temperature ranges.

RF Switches Applications

• Wireless infrastructure base station front-end modules
• Test and measurement equipment signal routing
• Satellite communication systems

RF Switches Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status as per manufacturer documentation. Confirm the package type matches the required PCB footprint, specifically the 24-QFN (4x4) dimensions. Ensure thermal management strategies align with the specified -40°C to +105°C operating range for the intended application environment.

RF Switches Selection Notes

Select this component when absorptive switching characteristics are required to minimize signal reflections and improve linearity in multi-port RF paths. Compare against reflective switch models if lower insertion loss is prioritized over isolation performance. Verify that the 4 GHz upper frequency limit meets the system's operational bandwidth requirements.

RF Switches Part Context

This part belongs to pSemi’s UltraCMOS family of radio frequency switches. These devices utilize silicon-based technology to deliver high performance in compact packages. The PE42452A-Z specifically targets applications needing reliable signal distribution among multiple antennas or paths in demanding RF environments.

RF Switches Replacement Considerations

Direct substitutes within the same family may include other SP5T variants from pSemi, such as the PE42452 series. Cross-reference pinouts and electrical specifications carefully to ensure compatibility with existing circuit designs without requiring layout modifications.
