SKY12245-492LF Block Diagram TM Skyworks Green products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Description TM Denition of Green , document number The SKY12245-492LF is a compact, integrated high-power SQ040074. single-pole, double-throw (SPDT) switch with driver circuit for TD-LTE applications. The part operates with a single +5 V supply and switches with a single control voltage (0 to 3 V). It can be tuned to specific RF bands within the range of 0.3 to 3.8 GHz by modifying select external SMT components. This device features low TX and RX insertion loss, high isolation with low DC power consumption and requires minimal external components, enabling a smaller PCB footprint. The device is provided in a 5 5 mm, 20-pin Quad Flat No-Lead (QFN) package. A functional block diagram is shown in Figure 1. Skyworks Solutions, Inc.
