Description

The M/A-COM MAMUSM0008 is a 0 to 750 pS variable
delay line controlled by 4 complementary bit pairs. It
provides the user with 50 pS delay step sizes for use in
standard wireless applications. The MAMUSM0008 is
particularly useful in providing time delay in the
cancellation loops of feed-forward amplifiers.
