4283-52

Overview

The pSemi PE4283-52 is a general-purpose Single-Pole Double-Throw (SPDT) RF switch utilizing UltraCMOS technology. It operates from DC to 4 GHz with a 50-ohm impedance. Key electrical specifications include 22 dB isolation and 0.7 dB insertion loss, measured at a test frequency of 2.5 GHz. The device supports a supply voltage range of 2V to 3.3V and employs a reflective topology. It is housed in an SC-70-6 package.

Feature Summary

• UltraCMOS technology implementation for high-performance RF switching
• General-purpose SPDT circuit configuration
• Reflective topology design

Applications

• General purpose RF signal routing
• Test and measurement equipment
• Wireless communication infrastructure

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering code matches the required variant. Check for discontinuation status as Peregrine Semiconductor has indicated potential phase-outs for certain 4283 series codes. Ensure compliance with RoHS and other relevant regulatory standards applicable to your region before finalizing procurement.

Selection Notes

Select this component when a DC-to-4 GHz SPDT switch is required for general applications. Consider the 0.7 dB insertion loss and 22 dB isolation metrics for signal integrity requirements. The SC-70-6 package suits space-constrained designs. Evaluate the 2V to 3.3V supply range against system power constraints. Compare against alternative switches if higher linearity or lower loss is needed.

Part Context

The PE4283-52 belongs to the Peregrine Semiconductor (pSemi) UltraCMOS family. This series focuses on RF switches leveraging proprietary silicon-on-insulator technology. The product line targets mobile, consumer, and infrastructure markets. The 4283 series specifically addresses general-purpose switching needs within the specified frequency range.

Replacement Considerations

Peregrine Semiconductor has announced discontinuation reviews for the 4283 series, including ordering codes 4283-00, 4283-51, and 4283-52. Designers should evaluate long-term availability risks. No public confirmed substitute part numbers are provided in the source documentation. Consult manufacturer resources for current lifecycle status.
