Description
The AS126-62 is a 4 port switch designed to combine T/R
and antenna changeover switching capability within one
device. This switch has two DC voltage controls and is
ideal for -5 V applications having low power consumption
requirements. The AS126-62 is suitable for cellular
wireless communication applications.
