Description
M/A-COM's MAMDCC0002 is a Vector Modulator that
significantly reduces the required board space compared to
hybrid solutions. The monolithic passive elements will
lead to greater repeatability lot-to-lot. Low amplitude rip-
ple will provide superior performance. High intercept and
compression points will contribute to more linear system
performance. MAMDCC0002 is ideally suited for wireless
infrastructure applications.
M/A-COM's MADRCC0002 Dual Linearizer is designed
to simplify the control of Vector Modulators. See
Figure 1 and App Note AN3001.
