For additional information, refer to Skyworks RF7 Denition of Green, document number SQ04-0074. RF8 Description Bias Decoder The SKY13418-485LF is a single-pole, eight-throw (SP8T) antenna switch. The high linearity performance and low insertion loss achieved by the SKY13418-485LF make it an ideal choice for main/diversity switching commonly used in LTE-based handsets, Figure 1. SKY13418-485LF Block Diagram data cards, and tablets that use antenna diversity solutions. The SKY13418-485LF is part of a scalable family of products that Switching is controlled by three CMOS/TTL-compatible control covers SP4T through SP8T switches that allow up to eight bands voltage inputs (V1, V2, and V3). Depending on the logic voltage of WCDMA/LTE: level applied to the control pins, the ANT pin is connected to one of eight switched RF input/output (I/O) ports (RF1 to RF8) using a SKY13414-485LF SP4T Antenna Switch (Data Sheet 201689) low insertion loss path, while the paths between the ANT pin and SKY13415-485LF SP5T Antenna Switch (Data Sheet 201704) the other RF pins are in a high isolation state. No external SKY13416-485LF SP6T Antenna Switch (Data Sheet 201679) blocking capacitors are required on the RF paths unless VDC is applied externally. SKY13417-485LF SP7T Antenna Switch (Data Sheet 201661) The SKY13418-485LF is manufactured in a compact, 14-pin 2.0 x SKY13418-485LF SP8T Antenna Switch (this Data Sheet) 2.0 mm, Quad Flat No-Lead (QFN) package. The symmetric port designs provide flexibility in signal routing for A functional block diagram is shown in Figure 1.
