4256-52

Overview

The PE4256-52 is an UltraCMOS RF switch IC designed for CATV applications, featuring a single-supply SPDT configuration. It operates from 0 Hz to 3 GHz with 1.2 dB insertion loss and 44 dB typical off-isolation. Built on Si technology, it supports SMD/SMT mounting within a -40°C to +85°C range. Available in Reel, Cut Tape, and MouseReel packages, this component integrates absorptive switching capabilities for high-performance signal routing.

Feature Summary

• Absorptive switching architecture minimizes signal reflections
• Single-supply operation simplifies power management
• High isolation performance ensures signal integrity

Applications

• CATV signal distribution networks
• RF signal routing in wireless infrastructure
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (e.g., -52) against official pSemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with standard surface-mount assembly processes. Cross-reference datasheet revision numbers to validate electrical parameters before integration into final designs.

Selection Notes

Select this component for applications requiring low insertion loss and high isolation across a broad frequency range up to 3 GHz. The UltraCMOS technology offers robust performance for CATV and general RF switching needs. Consider thermal management requirements within the specified operating temperature range during PCB layout.

Part Context

This part belongs to the UltraCMOS series of RF switches from pSemi. It complements other SPDT and SPST variants in the portfolio, offering specialized features for cable television and broadband applications. The family emphasizes high linearity and low power consumption.

Replacement Considerations
