AS119-12
Description
The AS119-12 is a reflective SPDT FET IC switch
designed for 1.9 GHz applications requiring high isolation.
The switch requires external DC blocking capacitors,
positive supply and two positive controls eliminating the
need for a negative voltage. The device is mounted in a
plastic SOIC-8 package for surface mounting. The
AS119-12 can be used in many analog and digital wireless
applications.
