SKY13414-485LF Block Diagram Description The SKY13414-485LF is a Single Pole, Four-Throw (SP4T) antenna switch. With an internal 50 Ω termination. The high linearity performance and low insertion loss achieved by the SKY13414-485LF 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 SKY13414-485LF 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 (this Data Sheet) SKY13415-485LF SP5T Antenna Switch (Data Sheet #201704) SKY13416-485LF SP6T Antenna Switch (Data Sheet #201679) SKY13417-485LF SP7T Antenna Switch (Data Sheet #201661) SKY13418-485LF SP8T Antenna Switch (Data Sheet #201712) 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 four switched RF outputs (RF1 to RF4) 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 SKY13414-485LF 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. 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.

Functional Description Electrical and Mechanical Specifications The SKY13414-485LF 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 SKY13414-485LF 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 four switched RF outputs or a 50 Ω termination. The state of the SKY13414-485LF is determined by the logic shown in Table 4. 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. 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.

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. ESD HANDLING: 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 when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times.
