Description
The SKY13267-321 is a monolithic DPDT switch fabricated using
Skyworks proprietary GaAs PHEMTs as the switching elements.
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.
