UPD5904T7K-E2-A

RF Switches Overview

The UPD5904T7K-E2-A is a single-pole four-throw (SP4T) RF switch IC manufactured by CEL. It operates within a frequency range of 50 MHz to 6 GHz, making it suitable for general-purpose high-frequency applications. The device is housed in a compact 12-QFN (2x2) package and supports supply voltages typically between 1.8 V and 3.6 V. Key electrical characteristics include low insertion loss and high isolation, ensuring efficient signal routing in wireless communication systems.

RF Switches Feature Summary

• Single-pole four-throw (SP4T) switching configuration for multi-path signal routing
• Wideband operation covering frequencies from 50 MHz up to 6 GHz
• Compact 12-pin QFN surface-mount package design
• Low power consumption suitable for portable wireless devices

RF Switches Applications

• Wireless local area network (WLAN) infrastructure
• Mobile phone antenna switching modules
• Software-defined radio (SDR) front ends
• Test and measurement equipment RF paths

RF Switches Procurement Notes

Verify the specific suffix E2-A against official CEL documentation to confirm pinout and electrical tolerances. Ensure compatibility with standard SMD/SMT assembly processes. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference part numbers with authorized distributors to avoid obsolete or counterfeit inventory. Validate operating temperature ranges against system environmental requirements before integration.

RF Switches Selection Notes

Select this component when a SP4T topology is required for frequencies extending to 6 GHz. Consider the 12-QFN footprint for space-constrained PCB layouts. Evaluate insertion loss and isolation specifications against link budget requirements. Compare supply voltage ranges with available system rails. Assess thermal performance under continuous RF load conditions relative to package capabilities.

RF Switches Part Context

This component belongs to the CEL UPD59xx series of RF switches, designed for broadband communication applications. The series offers various configurations including SPDT and SP4T options. The UPD5904 variant specifically provides four output ports controlled by a single input, facilitating complex signal path management in modern RF front-end designs without requiring multiple discrete components.

RF Switches Replacement Considerations

The UPD5902T7K-A is a related SPDT variant within the same family but offers different port counts. Direct substitution requires verifying that the application can accommodate the change from four throws to two. Check if the control logic and pinout remain compatible. Consult CEL for updated equivalents if the E2-A suffix indicates end-of-life status.
