SKY13347-360LF Signal Descriptions Pin Name Description Pin Name Description 1 N/C No connection. May be connected to ground with no change in performance. 5 RF1 RF port 1. Must be DC blocked. 2 GND Ground 6 VS DC bias voltage. Refer to Table 4. 3 GND Ground 7 V1 DC control voltage. Refer to Table 4. 4 N/C No connection. May be connected to ground with no change in performance. 8 RF2 RF port 2. Must be DC blocked. Functional Description Electrical and Mechanical Specifications Switching is controlled by a single control voltage on the V1 pin. Depending on the logic applied to the control pin, the RF1 and RF2 signals (pins 5 and 8, respectively) are connected to each other either by a low insertion loss path or a high isolation path. The absolute maximum ratings of the SKY13347-360LF are provided in Table 2. Electrical specifications are provided in Table 3. Both RF ports of the switch require DC blocking capacitors. The value of either blocking capacitor determines the low frequency of operation. Typical performance characteristics of the SKY13347-360LF are illustrated in Figures 3 through 8. The state of the SKY13347-360LF is determined by the logic provided in Table 4. 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.
