Note 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.
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 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).
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.
