Product Description
The TGS4307 is a 77 GHz switch matrix for
use in automotive radar transceivers. The
switch is designed using TriQuint’s proven
VPIN diode production process.
Three antenna ports may be selected
independently and directed to a source (J5)
or a receive (J4) port. Additionally, the
source port can be directed to the LO port
for use with a downconverting mixer.
