Description The SKY13414-485LF is a single pole, four-throw (SP4T) antenna Switching is controlled by three CMOS/TTL-compatible control switch with an internal 50 termination. The high-linearity voltage inputs (V1, V2, and V3). Depending on the logic voltage performance and low insertion loss achieved by the level applied to the control pins, the ANT pin is connected to one SKY13414-485LF make it an ideal choice for main/diversity of four switched RF outputs (RF1 to RF4) using a low insertion switching commonly used in LTE-based handsets, data cards, loss path, while the paths between the ANT pin and the other RF and tablets that use antenna diversity solutions. pins are in a high isolation state. The antenna path can also be closed on a 50 load when it needs to be terminated. The 50 The SKY13414-485LF is part of a scalable family of products that load is internally grounded. No external blocking capacitors are covers SP4T through SP8T switches that allow up to eight bands required on the RF paths unless VDC is externally applied. of WCDMA/LTE: The SKY13414-485LF is manufactured in a compact, 14-pin SKY13414-485LF SP4T Antenna Switch (this Data Sheet) 2.0 x 2.0 mm, Quad Flat No-Lead (QFN) package.

Electrical specifications are provided in blocking capacitors on the RF ports. No external components are Table 3. required for proper operation. DC decoupling capacitors may be The state of the SKY13414-485LF is determined by the logic added on the VDD and control lines if necessary. shown in Table 4. Switching is controlled by three control voltage inputs, V1, V2, and The isolation matrix shown in Table 5 provides the port-to-port V3. Depending on the logic voltage level applied to the control and antenna-to-port isolation for all available RF states at four pins, the antenna pin is connected to one of four switched RF different frequencies: 1.0 GHz, 2.0 GHz, 2.7 GHz, and 3.8 GHz. outputs or a 50 termination. 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 A typical. Skyworks Solutions, Inc.
