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 SKY1...
