Description  

The SKY13453-385LF is a single-pole, double-throw (SPDT)  

switch intended for mode switching in pre-power amplifier (PA)  

cellular or WLAN applications. Using advanced switching  

technologies, the SKY13453-385LF maintains low insertion loss  

and high isolation for all switching paths.  

The high-linearity performance and low insertion loss achieved by  

the switch make it an ideal choice for mode switching before the  

PA in cellular applications. Depending on the logic voltage applied  

to the control pin (VCTL), the RFC pin is connected to one of the  

two switched RF outputs, RF1 or RF2, using a low insertion loss  

path, while the path between the RFC pin and the other RF path is  

in a high isolation state.

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

:

A

lthough 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.
