DATA SHEET SKY13415-485LF: 0.1 to 3.0 GHz SP5T Antenna Switch Applications Any 2G/3G/4G antenna diversity or LTE (TDD/FDD) transmit/receive system RF1 RF2 Description The SKY13415-485LF is a Single Pole, Five-Throw (SP5T) antenna switch with an internal 50 Ω termination. The high linearity performance and low insertion loss achieved by the SKY13415-485LF 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 SKY13415-485LF 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 (this Data Sheet) SKY13416-485LF SP6T Antenna Switch (Data Sheet #201679) ANT RF5 50 Ω Bias Decoder V1 Skyworks Green™ products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of Green™, document number SQ04-0074. RF4 V2 Small QFN (14-pin, 2.0 x 2.0 mm) package (MSL1, 260 C per JEDEC J-STD-020) RF3 V3 Broadband frequency range: 0.1 to 3.0 GHz Low insertion loss: 0.45 dB typical @ 2.7 GHz High isolation: >30 dB @ 2.7 GHz Internal 50 Ω port to control diversity antenna impedance when device is not in use Integrated logic VDD Features S2668 Figure 1. SKY13415-485LF Block Diagram 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 five switched RF outputs (RF1 to RF5) 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 externally applied. The SKY13415-485LF 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. SKY13417-485LF SP7T Antenna Switch (Data Sheet #201661) 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.

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 SKY13415-485LF 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 SKY13415-485LF 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 five switched RF outputs or a 50 Ω termination. The isolation matrix shown in Table 5 provides the port-to-port and antenna-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 SKY13415-485LF is determined by the logic shown in Table 4. Shutdown mode is enabled by connecting all three control pins (V1, V2, and V3) to logic high. This mode reduces the overall current consumption of the device to 5 μA typical.
