Figure 1. SKY13526-485LF Block Diagram For additional information, refer to Skyworks TM Denition of Green , document number SQ040074. Depending on the logic applied to the decoder, the antenna pin is connected to one of six switched RF ports using a low insertion loss path, while the paths between the antenna pin and the other Description RF pins are in a high isolation state. Switching is controlled by the The SKY13526-485LF is a single-pole, six-throw (SP6T) antenna MIPI decoder. There is an external MIPI select pin that enables switch with a Mobile Industry Processor Interface (MIPI). how the switch responds to power mode triggers. When this pin is Using advanced switching technologies, the SKY13526-485LF grounded, the switch responds to any of the power mode triggers. maintains low insertion loss and high isolation for both transmit When this pin is left open, the switch responds to individual and receive switching paths. The high linearity performance and power mode triggers. No external DC blocking capacitors are low insertion loss achieved by the SKY13526-485LF makes it an required on the RF paths as long as no DC voltage is applied. ideal choice for UMTS, CDMA2000, EDGE, and LTE applications. The SKY13526-485LF is manufactured in a compact, 2 x 2 mm, 14-pin surface mount 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.
