• GaAs MMIC construction ensuring low cost and high reliability
• Wide frequency coverage from DC to 3 GHz suitable for multiple wireless standards
• Lead-free SOT-26 surface mount plastic package for compact integration

RF Switches Applications

• CDMA wireless communication systems
• GSM mobile phone applications
• PCS and DCS1800 base stations and handsets
• WCDMA signal routing

RF Switches Procurement Notes

Verify the specific suffix TR3000 indicates the tape-and-reel packaging quantity when ordering. Confirm RoHS compliance status as required by your manufacturing standards. Ensure the SOT-26 footprint matches your PCB layout design. Cross-reference the manufacturer's latest datasheet for any updates on pin configuration or handling precautions before finalizing procurement.

RF Switches Selection Notes

Select this component when an absorptive switch topology is preferred over reflective types to minimize VSWR degradation across the band. The 3 GHz upper frequency limit makes it suitable for legacy and current cellular bands up to 1800 MHz. Consider the SOT-26 package size constraints and thermal dissipation capabilities for your specific enclosure design compared to larger packages offering higher power handling.
