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)

Figure 1. SKY13415-485LF 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 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.
 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.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
Functional Description
Electrical and Mechanical Specifications
The SKY13415-485LF includes an internal negative voltage
generator and decoder that eliminate the need for external DC
blocking capacitors on the RF ports. No external components are
required for proper operation. DC decoupling capacitors may be
added on the VDD and control lines if necessary.
The absolute maximum ratings of the SKY13415-485LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
Switching is controlled by three control voltage inputs, V1, V2, and
V3. Depending on the logic voltage level applied to the control
pins, the antenna pin is connected to one of five switched RF
outputs or a 50 Ω termination.
The isolation matrix shown in Table 5 provides the port-to-port
and antenna-to-port isolation for all available RF states at three
different frequencies: 1.0 GHz, 2.0 GHz, and 2.7 GHz.
The state of the SKY13415-485LF is determined by the logic
shown in Table 4.
Shutdown mode is enabled by connecting all three control pins
(V1, V2, and V3) to logic high. This mode reduces the overall
current consumption of the device to 5 μA typical.
