4268-52

Overview

The PE4268-52 is an SP6T RF UltraCMOS switch designed for GSM handset antenna switching and other IF/RF applications. It operates from 100 to 3000 MHz with a 2.6 V supply. Key electrical parameters include low TX insertion loss of 0.55 dB at 900 MHz and 0.7 dB at 1900 MHz, alongside TX-RX isolation of 48 dB at 900 MHz and 40 dB at 1900 MHz. It features 1500 V HBM ESD tolerance and low harmonics (-84 dBc at 2fo, -70 dBc at 3fo at +35 dBm input). The device utilizes three-pin CMOS logic control and requires no blocking capacitors.

Feature Summary

• SP6T configuration with two high-power paths and four low-power paths
• Three-pin CMOS logic control with integral decoder/driver
• High ESD tolerance of 1500 V at all ports
• No blocking capacitor requirements

Applications

• Quad-Band GSM Handset Antenna Switch Module Market
• IF and RF applications requiring broadband performance
• Low power path switching in mobile devices

Procurement Notes

Verify the specific suffix (e.g., -52) against official pSemi documentation to confirm RoHS compliance status and exact package marking. Ensure the ordering part number matches the required lead-free specifications. Cross-reference the datasheet revision to confirm pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component for designs requiring integrated SP6T switching in compact mobile form factors. The UltraCMOS process offers GaAs-like performance with CMOS integration benefits. Consider the 2.6 V operating voltage and three-pin control interface for system compatibility. Verify that the 100–3000 MHz frequency range meets the specific application bandwidth requirements.

Part Context

The PE4268-52 belongs to the UltraCMOS family manufactured using Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS process. This technology aims to provide the performance of GaAs with the economy and integration of conventional CMOS. The device is housed in a 20-lead 4x4 mm QFN package, suitable for surface mount assembly in space-constrained portable electronics.
