Overview

The SKY13268-344LF is a monolithic SPDT switch fabricated using Skyworks Solutions’ proprietary GaAs pHEMTs as the switching elements. This wideband switch operates with RF signals from 300 kHz to 3 GHz. The RF signal paths within the SKY13268-344LF are fully bilateral. Ports J2 and J3, RF input/output terminals are reflective. 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 pin, the Common RF pin, J1, is connected to one of two switched RF pins (J2 or J3) via a low insertion loss path, while the path between the RF common and the other RF pin is in its high isolation state. DC power consumption is very low, 100 μA maximum with control voltage of 3 V. The switch can operate over the temperature range of -40 °C to 85 °C. An evaluation board is available upon request.
