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.

 SKY13414-485LF SP4T Antenna Switch (Data Sheet #201689)

 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 (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 V

DC 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.

Functional Description

The SKY13418-485LF 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 eight switched RF

outputs.

The recommended startup sequence is:

1. Apply VDD

2. Apply V1, V2, and V3 voltages

3. Apply RF input

The device must be turned off in reverse order.

Electrical and Mechanical Specifications

The absolute maximum ratings of the SKY13418-485LF are

provided in Table 2. Electrical specifications are provided in

Table 3.

The state of the SKY13418-485LF is determined by the logic

shown in Table 4.

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