Decoder For additional information, refer to Skyworks TM Denition of Green , document number SQ040074. Figure 1. SKY13412-487LF Block Diagram Description Switching is controlled by an integrated GPIO interface. The SKY13412-487LF is a single pole, twelve throw (SP12T) Depending on the logic applied to the decoder, the antenna pin is antenna switch with integrated GSM transmit harmonic filter. The connected to one of 12 switched RF ports using a low insertion SKY13412-487LF maintains a high linearity, high isolation, and loss path, while the paths between the antenna pin and the other low insertion loss performance, which makes it an ideal choice for RF pins are in a high isolation state. No external DC blocking UMTS, CDMA2000, EDGE, GSM, and LTE applications. capacitors are required on the RF paths. The design features two dedicated GSM transmit ports. The The SKY13412-487LF is manufactured in a compact, remaining ten ports are suitable for WCDMA transmit/receive and 3.0 x 3.8 x 0.75 mm, 30-pin surface mount Quad Flat No-Lead GSM receive functions. Three transmit ports have been (QFN) package. specifically designed to provide optimal LTE Band 13 performance. The switch exhibits an excellent triple beat ratio and A functional block diagram is shown in Figure 1. The pin second/third order modulation distortion performance. configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.
