This wideband switch operates with RF signals from LF–6 GHz. The RF signal paths within the SKY13267-321 are fully bilateral. Switching is controlled via two control voltage inputs, which are compatible with CMOS logic levels. Depending upon the logic voltage level applied to the control voltage pins, the Tx input pin is connected to one of two antenna ports (ANT1 or ANT2) via a low insertion loss path, while the path between the Rx pin is connected to the other antenna port. When the control voltages are toggled, the connections between the Tx input and Rx output pins and the antenna ports are toggled as well. DC power consumption is very low, 15 µA maximum with control voltage of 5 V. The switch can operate over the temperature range of -40 °C to +85 °C. This part is available in a lead (Pb)-free and RoHs-compliant package as part number SKY13267-321LF. An evaluation board is available upon request. .

Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) 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 must be employed at all times.
