Features - Broadband frequency range: 0.4 to 2.7 GHz - Single, positive DC power supply (2.5 to 3.3 V) - Excellent Band 13 2nd 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 Description The SKY13404-466LF is a Single Pole, Ten-Throw (SP10T) antenna switch with an integrated General Purpose Input/Output (GPIO) interface and dual low-pass harmonic filters. The switch has eight transmit/receive ports, any of which can be used for WCDMA transmit/receive or GSM receive functions. Using advance switching technologies, the SKY13404-466LF maintains low insertion loss and high isolation for both transmit and receive switching paths. The switch also exhibits an excellent triple beat ratio and 2nd/3rd order modulation distortion performance. Switching is controlled by an integrated GPIO interface. Depending on the logic applied to the decoder, the antenna pin is connected to one of ten switched RF ports using a low insertion loss path, while the paths between the antenna pin and the other RF pins are in a high isolation state. No external DC blocking capacitors are required on the RF paths. The SKY13404-466LF is manufactured in a pact, 2.6 x 3.4 mm, 26-pin 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.
