Functional Description Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13472-460LF are The SKY13472-460LF includes an internal negative voltage provided in Table 2. Electrical specifications are provided in generator and decoder that eliminate the need for external DC Table 3. blocking capacitors on the RF ports. No external components are required for proper operation. DC decoupling capacitors may be The state of the SKY13472-460LF is determined by the logic added on the VDD and control lines if necessary. provided in Table 4. Switching is controlled by two control voltage inputs, V1 and V2. Typical performance characteristics of the SKY13472-460LF are Depending on the logic voltage level applied to the control pins, illustrated in Figures 3 through 5. the RFC (RF common) pin is connected to one of two switched RF outputs (J1 or J2) through a low insertion path, while the path between the RFC pin and the other RF pins is in a high isolation state. Shutdown mode is enabled by connecting all control pins to logic low. This mode reduces the overall current consumption of the device to 5 A, typical. To prevent the switch from accidentally entering shutdown mode during switching, all states must be set to logic low for at least 20 s. When exiting shutdown mode, the switch as a 10.5 s startup time before switching occurs. 1 Table 2.

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. 2 Any bias voltage applied to the V1 or V2 pins may damage the device if there is no bias voltage also present on the VDD pin. Maximum control voltage cannot exceed VDD. 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. Skyworks Solutions, Inc.
