DATA SHEET SKY13550-667LF: 0.4 to 3.8 GHz DP8T (SP4T/SP4T) Main/Receive Diversity Switch with MIPI RFFE Interface for Carrier Aggregation Applications TRXA1 3G/4G multimode cellular handsets (UMTS and CDMA2000) TRXA2 Carrier aggregation diversity ANT A TRXA3 TRXA4 Features Broadband frequency range: 0.4 to 3.8 GHz TRXB1 Single, positive DC power supply (2.5 to 4.8 V) TRXB2 nd Excellent Band 13 2 harmonic performance ANT B TRXB3 rd Excellent Band 17 3 harmonic performance TRXB4 Integrated, programmable MIPI interface using separate registers for ANT A and ANT B bands Dual antenna ports can be connected externally to a diplexer Bias Logic Block Small QFN (14-pin, 1.6 x 2.0 x 0.55 mm) package (MSL1, 260 C per JEDEC J-STD-020) 203284D-001 TM Skyworks Green products are compliant with Figure 1. SKY13550-667LF Block Diagram all applicable legislation and are halogen-free. For additional information, refer to Skyworks TM Denition of Green , document number Switching is controlled by an integrated MIPI decoder. The two SQ040074. switches can be configured independently. There are separate registers for each SP4T. No external DC blocking capacitors are Description required on the RF paths as long as no DC voltage is applied to The SKY13550-667LF is a dual single-pole, four-throw (2xSP4T) those paths. Mobile Industry Processor Interface (MIPI) controlled antenna The SKY13550-667LF is manufactured in a compact, switch designed specifically for receive diversity in carrier 1.6 x 2.0 x 0.55 mm, 14-pin surface-mount Quad Flat No-Lead aggregation applications. (QFN) package. The 2xSP4T switch is optimized for broadband performance. A functional block diagram is shown in Figure 1. The pin Using advanced switching technologies, the SKY13550-667LF configuration and package are shown in Figure 2. Signal pin maintains low insertion loss and high isolation for all switching assignments and functional pin descriptions are provided in paths. The high linearity performance and low insertion loss Table 1. achieved by the SKY13550-667LF makes it an ideal choice for carrier aggregation applications. The switch also exhibits excellent second/third order intermodulation distortion (IMD2/IMD3) performance. Skyworks Solutions, Inc.
