Description
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,
data cards, and tablets that use antenna diversity solutions.
The SKY13418-485LF is part of a scalable family of products that
covers SP4T through SP8T switches that allow up to eight bands
of WCDMA/LTE.

SKY13417-485LF SP7T Antenna Switch (Data Sheet #201661)
SKY13418-485LF SP8T Antenna Switch (this Data Sheet)
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.

Figure 1. SKY13418-485LF Block Diagram
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 eight switched RF input/output (I/O) ports (RF1 to RF8) 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
applied externally.
The SKY13418-485LF 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.

Notes:
1. All measurements are in millimeters.
2. Dimensions and tolerances according to ASME Y14.5M-1994.
3. Coplanarity applies to the terminals and all other bottom surface metallization.
4. Dimension applies to metallized terminal. If the terminal has a radius on its end,
the width dimension should not be measured in that radius area.
