DATA SHEET SKY13417-485LF: 0.1-3.0 GHz SP7T Antenna Switch Applications • Any 2G/3G/4G antenna diversity or LTE (TDD/FDD) transmit/receive system for which GSM transmit is not required Features • Broadband frequency range: 0.1 to 3.0 GHz • Low insertion loss: 0.7 dB typical @ 2.7 GHz • High isolation: >20 dB @ 2.7 GHz • Integrated logic • Internal 50 Ω port to control diversity antenna impedance when device is not in use • Small QFN (14-pin, 2.0 x 2.0 mm) package (MSL1, 260 °C per JEDEC J-STD-020) Figure 1. SKY13417-485LF Block Diagram Description The SKY13417-485LF is a Single Pole, Seven-Throw (SP7T) switch with an internal 50 Ω termination. The high linearity performance and low insertion loss achieved by the SKY13417485LF make it an ideal choice for main/diversity switching commonly used in LTE-based handsets, data cards, and tablets that use antenna diversity solutions. The SKY13417-485LF is part of a scalable family of products that covers SP4T through SP8T switches that allow up to eight bands of WCDMA/LTE. • SKY13414-485LF SP4T Antenna Switch (Data Sheet #201689) • SKY13415-485LF SP5T Antenna Switch (Data Sheet #201704) • SKY13416-485LF SP6T Antenna Switch (Data Sheet #201679) • SKY13417-485LF SP7T Antenna Switch (this Data Sheet) • SKY13418-485LF SP8T Antenna Switch (Data Sheet #201712) The symmetric port designs provide flexibility in signal routing for both receive diversity and higher power TD-SCDMA/TDD-LTE, WCDMA/FDD, and LTE transmit/receive applications. Switching is controlled by three CMOS/TTL-compatible control voltage inputs (V1, V2, and V3). Depending on the logic voltage level applied to the control pins, the ANT pin is connected to one of seven switched RF input/output (I/O) ports (RF1 to RF7) using a low insertion loss path, while the paths between the ANT pin and the other RF pins are in a high isolation state. The antenna path can also be closed on a 50 Ω load when it needs to be terminated. The 50 Ω load is internally grounded. No external blocking capacitors are required on the RF paths unless VDC is applied externally. The SKY13417-485LF is manufactured in a compact, 14-pin 2.0 x 2.0 mm, 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. Functional Description Electrical and Mechanical Specifications The SKY13417-485LF includes an internal negative voltage generator and decoder that eliminate the need for external DC blocking capacitors on the RF ports. No external components are required for proper operation. DC decoupling capacitors may be added on the VDD and control lines if necessary. The absolute maximum ratings of the SKY13417-485LF are provided in Table 2. Electrical specifications are provided in Table 3. Switching is controlled by three control voltage inputs, V1, V2, and V3. Depending on the logic voltage level applied to the control pins, the antenna pin is connected to one of seven switched RF outputs or a 50 Ω termination. The isolation matrix shown in Table 5 provides the port-to-port isolation for all available RF states at three different frequencies: 1.0 GHz, 2.0 GHz, and 2.7 GHz. The state of the SKY13417-485LF is determined by the logic shown in Table 4. The recommended startup sequence is: 1. Apply VDD 2. Apply V1, V2, and V3 voltages 3. Apply RF input The device must be turned off in reverse order.
