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.
The switch is manufactured in a compact, 1 x 1 mm, 6-pin 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.

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.
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.
