Description
The SKY13330-397LF is a CMOS, silicon-on-insulator (SOI)
single-pole, double-throw (SPDT) switch. The high linearity and
low insertion loss of the SKY13330-397LF make it an ideal choice
for WCDMA handset and data card applications.
The switch is a “reflective short” on the isolated port.
The SKY13330-397LF SP2T switch is provided in a compact Quad
Flat No-Lead (QFN) 2 x 2 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.

Functional Description
Electrical and Mechanical Specifications
The SKY13330-397LF is designed for medium to high power
WCDMA handset and data card switching applications. The device
can also be used in a variety of other applications that require
high performance RF switching such as WLANs (a/b/g/n).
The absolute maximum ratings of the SKY13330-397LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
An internal negative voltage generator and decoder eliminate the
need for external DC blocking capacitors on the RF ports unless
VDC is externally applied.
Switching is controlled by one voltage input (CTRL). Depending on
the logic voltage level applied to the control pin, the RF1 pin is
connected to one of two switched RF outputs (RF2 or RF3) using a
low insertion loss path, while the path between the RF1 pin and
the other RF output pin is in a high isolation state.
An internal decoder is used to provide the correct logic to the
switch.
Shutdown mode is enabled by connecting the ENABLE pin to logic
low. Shutdown mode reduces the overall current consumption of
the device to 7 μA, typical.
The state of the SKY13330-397LF is determined by the logic
provided in Table 4.
Typical performance characteristics of the SKY13330-397LF are
illustrated in Figures 3 through 5.

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.
