DATA SHEET SKY13404-466LF: 0.4-2.7 GHz SP10T Switch with GPIO Interface Applications 2G/3G multimode cellular handsets (UMTS, CDMA2000, EDGE, GSM) Embedded data cards Features Broadband frequency range: 0.4 to 2.7 GHz Single, positive DC power supply (2.5 to 3.3 V) nd Excellent Band 13 2 harmonic rejection Integrated, low-pass harmonic filter for GSM transmit paths Integrated GPIO interface Any of eight TRX ports can be used for WCDMA transmit/receive or GSM receive functions Small QFN (26-pin, 2.6 x 3.4 mm) package (MSL1, 260 C per JEDEC J-STD-020) Figure 1. SKY13404-466LF Block Diagram Switching is controlled by an integrated GPIO interface. Depending Description on the logic applied to the decoder, the antenna pin is connected The SKY13404-466LF is a Single Pole, Ten-Throw (SP10T) to one of ten switched RF ports using a low insertion loss path, antenna switch with an integrated General Purpose Input/Output while the paths between the antenna pin and the other RF pins are (GPIO) interface and dual low-pass harmonic filters. The switch in a high isolation state. No external DC blocking capacitors are has eight transmit/receive ports, any of which can be used for required on the RF paths. WCDMA transmit/receive or GSM receive functions. The SKY13404-466LF is manufactured in a compact, Using advance switching technologies, the SKY13404-466LF 2.6 x 3.4 mm, 26-pin Quad Flat No-Lead (QFN) package. maintains low insertion loss and high isolation for both transmit A functional block diagram is shown in Figure 1. The pin and receive switching paths. The switch also exhibits an excellent nd rd configuration and package are shown in Figure 2. Signal pin triple beat ratio and 2 /3 order modulation distortion nd assignments and functional pin descriptions are provided in performance. Band 13 2 harmonic requirements can be met Table 1. without the use of an external filter. Skyworks Solutions, Inc.
