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.

Figure 1. SKY13414-485LF 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 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

Table 1.

Functional Description

The SKY13414-485LF 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.

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 four switched RF

outputs or a 50 Ω termination.

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.

Electrical and Mechanical Specifications

The absolute maximum ratings of the SKY13414-485LF are

provided in Table 2. Electrical specifications are provided in

Table 3.

The state of the SKY13414-485LF is determined by the logic

shown in Table 4.

The isolation matrix shown in Table 5 provides the port-to-port

and antenna-to-port isolation for all available RF states at four

different frequencies: 1.0 GHz, 2.0 GHz, 2.7 GHz, and 3.8 GHz.

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.

ESD HANDLING: 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 when handling or transporting. Static charges may easily produce

potentials of several kilovolts on the human body or equipment, which can discharge without detection.

Industry-standard ESD handling precautions should be used at all times.
