Description
The AS121-12 SPST IC FET switch is non-reflective on
both input and output. This device has been designed for
high isolation switching applications and is mounted in the
SOIC-8 package. For positive operation, the switch
requires DC blocking capacitors on RF lines, a positive
supply and two complementary positive controls. Ideal
building block for base station switching applications.
