Description

The SKY13414-485LF is a single pole, four-throw (SP4T) antenna

switch with an internal 50 Ω termination. The high-linearity

performance and low insertion loss achieved by the

SKY13414-485LF 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 SKY13414-485LF is part of a scalable family of products that

covers SP4T through SP8T switches that allow up to eight bands

of WCDMA/LTE:

 SKY13414-485LF SP4T Antenna Switch (this Data Sheet)

 SKY13415-485LF SP5T Antenna Switch (Data Sheet #201704)

 SKY13416-485LF SP6T Antenna Switch (Data Sheet #201679)

 SKY13417-485LF SP7T Antenna Switch (Data Sheet #201661)

 SKY13418-485LF SP8T Antenna Switch (Data Sheet #201712)

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 four switched RF outputs (RF1 to RF4) using a low insertion

loss path, while the paths between the ANT pin and the other RF

pins are in a high isolation state. The antenna path can also be

closed on a 50 Ω load when it needs to be terminated. The 50 Ω

load is internally grounded. No external blocking capacitors are

required on the RF paths unless VDC is externally applied.

The SKY13414-485LF 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
