Additional Details

The SKY13415-485LF2 operates within a specific frequency range, typically covering cellular, WLAN, and other wireless bands. The key specifications include insertion loss, isolation, return loss, switching speed, and power handling capability. The specific values for these parameters can be found in the product datasheet provided by Skyworks Solutions Inc.

The switch is controlled by applying a positive voltage to the control pins. Depending on the control voltage levels, one of the two output paths is selected, allowing for flexible signal routing. The high isolation between the output paths ensures that signals are routed correctly and that unwanted signals are suppressed.
