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) • 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. Band 13 2nd harmonic requirements can be met without the use of an external filter. 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 compact, 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.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13404-466LF are provided in Table 2. Electrical specifications are provided in Tables 3 through 6. Table 7 provides the control logic for the SKY13404-466LF. Typical performance characteristics of the SKY13404-466LF are illustrated in Figures 3 to 10. The isolation matrix shown in Table 8 provides the port-to-port isolation for all available RF states at three different frequencies: 915 MHz, 1910 MHz, and 2700 MHz. Figure 11 illustrates the test setup used to measure data for Figure 7. This industry standardized test is used to simulate the WCDMA Band 1 linearity of the antenna switch. A +20 dBm Continuous Wave (CW) signal, fFUND, is sequentially applied to the TRX1 through TRX8 ports, while a –15 dBm CW blocker signal, fBLK, is applied to the ANT port. The resulting 3rd Order Intermodulation Distortion (IMD3), fRX, is measured over all phases of fFUND. The SKY13404-466LF exhibits exceptional performance for all TRX ports.
