Description
RDASW91 is a single pole nine throw (SP9T)
antenna switch module. RDASW91 is ideally
suited for applications where high power, low
control voltage, low insertion loss, high
isolation, small size and low cost are required.
Typical applications are for handset systems that
connect separate transmit and receive functions
to a common antenna, as well as other related
handset and general purpose applications.
