Description
The SKY13415-485LF is a single pole, five-throw (SP5T) antenna
switch with an internal 50 Ω termination. The high linearity
performance and low insertion loss achieved by the
SKY13415-485LF 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 SKY13415-485LF 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 (Data Sheet #201689)
 SKY13415-485LF SP5T Antenna Switch (this Data Sheet)
 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 five switched RF outputs (RF1 to RF5) 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 SKY13415-485LF 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.
