Introduction

The SKY13416-485LF is a single pole, six-throw (SP6T) antenna switch. The high-linearity performance and low insertion loss achieved by the SKY13416-485LF 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 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 six switched RF outputs (RF1 to RF6) using a low insertion loss path, while the paths between the ANT pin and the other RF pins are in a high isolation state. No external blocking capacitors are required on the RF paths unless VDC is externally applied. The SKY13416-485LF is manufactured in a compact, 14-pin 2.0×2.0 mm, Quad Flat No-Lead (QFN) package. The SKY13416-485LF 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. 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 six switched RF outputs. A seventh state enables RF3 and RF5 at the same time. The output power measured at RF3 and RF5 in this state is 3 dB less than the typical insertion loss. 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.
