Description
The SKY13397-388LF is a double-pole, five-throw (DP5T) switch
designed for broadband, high-power switching applications that
demand low harmonics and low insertion loss. The switch is
optimized for 3G WCDMA applications.
The SKY13397-388LF features integrated logic that uses only two
control lines for switch operation. The low current consumption of
the device makes it very suitable for battery-operated
applications.
The switch is manufactured using a state of the art Silicon on
Insulator (SOI) process, and is provided in a compact Quad Flat
No-Lead (QFN) 2.3 x 2.3 mm 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.

Note:
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.
CAUTION: 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. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
Functional Description
The SKY13397-388LF 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 two control voltage inputs, GPIO1 and
GPIO2. Depending on the logic voltage level applied to the control
pins, the OUT1 signal (pin 4) is connected to one of two switched
RF inputs (IN1A or IN1B) through a low insertion loss path, while
the OUT2 signal (pin 2) is simultaneously switched to one of three
RF inputs (IN2A, IN2B, IN2C).
For proper switching operation, the SKY13397-388LF must be set
to a state for a minimum of 10 μs before changing to a different
state.
Shutdown mode is enabled by connecting both control pins to
logic low. This mode reduces the overall current consumption of
the device to 5 μA, typical. To prevent the switch from
accidentally entering shutdown mode during switching, caution
must be taken to avoid having both control signals (GPIO1 and
GPIO2) set to logic low for more than 500 ns. When exiting
shutdown mode, the switch has a 25 μs startup time before
switching occurs.

Electrical and Mechanical Specifications
I/O (GPIO) pins 15 and 16 with VDD = high. When VDD is high, the
switch is active and its state is controlled as described in Table 4.
When the switch is in standby mode, all paths are not operating.
The absolute maximum ratings of the SKY13397-388LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
The SKY13397-388LF may be used in one of two modes: active
and standby. These modes are controlled by the General Purpose
