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.
