Description
The SKY13268-344LF is a monolithic SPDT switch, fabricated
using Skyworks 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 J 2 and J 3 , 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, J 1 , is connected to one of two switched RF pins (J 2 or J 3 ) 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 con-
trol voltage of 3 V. The switch can operate over the temperature
range of -40 °C to +95 °C.
An evaluation board is available upon request.
