Description
The SKY13489-001 is a single-pole, double-throw (SPDT)
LTE/WCDMA/GSM transmit switch. Switching is controlled by an
integrated GPIO interface with a single control pin. Depending on
the logic voltage level applied to the control pin, the antenna port
is connected to one of the switched RF outputs (RF1 or RF2)
through a low insertion loss path, while the path between the
antenna port and the other RF port is in a high isolation state.
No external DC blocking capacitors are required as long as no DC
voltage is applied on any RF path.

The SKY13489-001 is provided in a compact 6-bump,
1.135 x 0.735 x 0.400 mm Wafer Level Chip Scale Package
(WLCSP) that meets requirements for board-level assembly.
Bump diameters are 217 microns with a minimum bump pitch of
400 microns.
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

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.
