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 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) 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 SKY13417- level applied to the control pins, the ANT pin is connected to one 485LF make it an ideal choice for main/diversity switching of seven switched RF input/output (I/O) ports (RF1 to RF7) using a commonly used in LTE-based handsets, data cards, and tablets low insertion loss path, while the paths between the ANT pin and that use antenna diversity solutions. the other RF pins are in a high isolation state. The antenna path The SKY13417-485LF is part of a scalable family of products that can also be closed on a 50 load when it needs to be covers SP4T through SP8T switches that allow up to eight bands terminated. The 50 load is internally grounded. No external of WCDMA/LTE. blocking capacitors are required on the RF paths unless VDC is applied externally. SKY13414-485LF SP4T Antenna Switch (Data Sheet 201689) The SKY13417-485LF is manufactured in a compact, 14-pin 2.0 x SKY13415-485LF SP5T Antenna Switch (Data Sheet 201704) 2.0 mm, Quad Flat No-Lead (QFN) package. SKY13416-485LF SP6T Antenna Switch (Data Sheet 201679) A functional block diagram is shown in Figure 1. The pin SKY13417-485LF SP7T Antenna Switch (this Data Sheet) configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in SKY13418-485LF SP8T Antenna Switch (Data Sheet 201712) 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.
