SKY66420-11

RF Front End (LNA + PA) Overview

The SKY66420-11 is an RF front-end module designed for sub-GHz applications, operating within the 860 MHz to 930 MHz frequency range. It features a noise figure of 1.5 dB and provides a gain of 16 dB. The device supports an operating supply voltage between 2 V and 4.8 V, with a typical operating current of 280 mA. Key performance metrics include an output third-order intercept point (OIP3) of -2 dBm and a P1dB compression point of 20 dBm. It is housed in a 16-pin MCM package.

RF Front End (LNA + PA) Procurement Notes

Verify component authenticity through authorized Skyworks distributors or direct manufacturer channels. Confirm lot traceability and humidity sensitivity level (MSL 3) handling requirements during storage and reflow soldering. Ensure packaging integrity matches specified reel or cut tape formats to prevent damage to the sensitive RF module during transit and assembly preparation.

RF Front End (LNA + PA) Selection Notes

Select this module when designing for sub-GHz bands requiring integrated amplification and low noise reception. Evaluate the 20 dBm P1dB limit against system power budget constraints. Consider the 280 mA supply current for battery life calculations in portable devices. Compare against discrete solutions if specific frequency agility outside the 860-930 MHz window is required.
