SKY65311-21

RF Front End (LNA + PA) Overview

The SKY65311-21 is a transmit/receive front-end module designed for operation in the 3.3–3.8 GHz frequency range. It integrates low-noise amplifier and power amplifier functions within a compact MCM-20 package. The component operates on a 3.3 V supply voltage with a typical current consumption of 110 mA. Key electrical specifications include a noise figure of 2.5 dB and a maximum output power of +20 dBm at 2.4 GHz, though performance degrades outside the primary band.

RF Front End (LNA + PA) Feature Summary

• Integrates low-noise amplifier and power amplifier functions into a single module
• Optimized for high-efficiency operation within the 3.3–3.8 GHz frequency range
• Designed for surface-mount installation using an MCM-20 package

RF Front End (LNA + PA) Applications

• Wireless communication systems requiring integrated RF front-end solutions
