SKY13547-490LF

RF Switches Overview

The SKY13547-490LF is a single-pole, double-throw (SPDT) RF switch IC designed for 75 Ω systems. It operates within a frequency range of 5 MHz to 1.8 GHz. The device features ultra-high linearity with a P1dB of 38 dBm and low insertion loss of 0.3 dB at 1.0 GHz. Typical off-isolation is 50 dB. It functions on a supply voltage between 2.5 V and 4.8 V. The component is housed in a compact 12-QFN (2x2 mm) package.

RF Switches Feature Summary

• Ultra-high linearity performance suitable for demanding signal integrity applications
• Low insertion loss characteristics optimized for efficient signal transmission
• High isolation levels to minimize signal leakage between ports

RF Switches Applications

• Wireless infrastructure equipment requiring high linearity switching
• Test and measurement instruments utilizing 75 Ω impedance standards
• Broadband communication systems operating up to 1.8 GHz

RF Switches Procurement Notes

Verify the specific suffix '490LF' to ensure compatibility with 75 Ω system designs. Confirm RoHS compliance status through official Skyworks documentation prior to integration. Check for any recent Product Change Notices (PCN) regarding assembly or material updates. Ensure the procurement channel provides authentic components from authorized distributors to guarantee reliability.

RF Switches Selection Notes

Select this component when designing circuits that require a 75 Ω interface rather than the standard 50 Ω configuration. Consider the 12-QFN package size for space-constrained layouts. Evaluate the 2.5 V to 4.8 V supply range against available power rails. Compare the 38 dBm P1dB specification against system dynamic range requirements to ensure adequate headroom.

RF Switches Part Context

This part belongs to the Skyworks SKY13547 series of SPDT switches. It is specifically engineered for 75 Ω applications, distinguishing it from similar 50 Ω variants in the portfolio. The device utilizes silicon technology for cost-effective performance in broadband scenarios.

RF Switches Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Verify pinout and electrical specifications carefully if considering alternative SPDT switches. Ensure replacement parts support the required 75 Ω impedance and 1.8 GHz frequency range.
