GaAs IC SPDT Switch DC–2.5 GHz
SSOP-8
AS328-62
Description
The AS328-62 is a low cost IC FET SPDT reflective switch
in a plastic SSOP-8 package for commercial low cost, low
power applications. The switch operates with -5, 0 V, but
operates with +5 V, 0 V when device is “floated”. Refer to
Application Notes for further information.
