TYP.
The AS127-59 is a 4 port switch designed to combine T/R
and antenna changeover switching capability within one
device. This switch has two 5 V controls and is ideal for
applications requiring low power consumption. The
AS127-59 has excellent performance to 2 GHz making it
suitable for dual-band handset designs.
