Figure 1. SKY13523-639LF Block Diagram Description The SKY13523-639LF is a single pole, triple-throw (SP3T) switch used for single-ended filter switching in cellular applications. The SKY13523-639LF maintains low insertion loss and high isolation for all switching paths. Depending on the logic voltage level applied to the control pins (V1 and V2), the RFC pin is connected to one of three switched RF outputs (RF1 to RF3) using a low insertion loss path, while the paths between the RFC pin and the other RF pins are in a high isolation state. The SKY13523-639LF is manufactured in a compact, 14-pin 1.6 x 1.6 mm, Quad Flat No-Lead (QFN) package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Skyworks Solutions, Inc.

Functional Description Electrical and Mechanical Specifications The SKY13523-639LF includes an internal decoder and internal The absolute maximum ratings of the SKY13523-639LF are blocking capacitors on the RF common ports. External DC provided in Table 2. Electrical specifications are provided in blocking capacitors are required on the RF1, RF2, and RF3 ports Table 3. for proper operation. DC decoupling capacitors may be added on The state of the SKY13523-639LF is determined by the logic the VDD and control lines if necessary. shown in Table 4. Switching is controlled by two control voltage inputs, V1 and V2. Depending on the logic voltage level applied to the control pins, the antenna pin is connected to one of three switched RF outputs.
