Functional Description The SKY13345-368LF 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 three control voltage inputs: V1, V2, and V3. Depending on the logic voltage level applied to the control pins, the RFC (RF common) pin is connected to one of three switched RF outputs (J1, J2, or J3) through a low insertion path, while the path between the RFC pin and the other RF pins is in a high isolation state. There is a fourth switching state that enables J2 and J3 at the same time. The output power measured at J2 and J3 in this state is 3 dB less than the insertion loss. For proper switching operation, the SKY13345-368LF must be set to a state for a minimum of 10 μs before changing to a different state. A typical switching diagram is shown in Figure 3. device to 5 μA, typical. To prevent the switch from accidentally entering shutdown mode during switching, caution must be taken to avoid having all three control signals (V1, V2, and V3) 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 The absolute maximum ratings of the SKY13345-368LF are provided in Table 2. Electrical specifications are provided in Table 3. The state of the SKY13345-368LF is determined by the logic provided in Table 4. Typical performance characteristics of the SKY13345-368LF are illustrated in Figures 4 through 7. Shutdown mode is enabled by connecting all control pins to logic low. This mode reduces the overall current consumption of the 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. Note 2: Any bias voltage applied to the V1, V2, or V3 pins may damage the device if there is no bias voltage also present on the VDD pin. 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.
