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. 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. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13330-397LF are provided in Table 2. Electrical specifications are provided in Table 3. 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. An internal decoder is used to provide the correct logic to the switch.
