Functional Description Electrical and Mechanical Specifications The SKY13395-397LF DPDT switch can be used to connect either RF port 1 or RF port 2 to either RF port 3 or RF port 4 by applying the proper bias to the two control pins (CTRL1 and CTRL2). When Port 1 is connected to Port 4 using a low loss path, Port 2 is connected to Port 3 also with a low loss path. When Port 1 is connected to Port 3 using low loss path, Port 2 is connected to Port 4 also with a low loss path. The absolute maximum ratings of the SKY13395-397LF are provided in Table 2. Electrical specifications are provided in Table 3. The DPDT switch is designed to maximize the isolation between ports to minimize coupling between RF paths. The state of the SKY13395-397LF is determined by the logic provided in Table 4. Typical performance characteristics of the SKY13395-397LF are illustrated in Figures 3 through 7. 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. 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.
