Description
M/A-COM's MAMDCC0005 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. MAMDCC0005 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.

4. Tic marks on x,y axes refer to reflection coefficient in increments of 0.1V. Reflection coefficients vary from -0.5 to +0.5 on both
the x and y axes.
5. Data is for vector modulators driven by linearizers. See Application Note AN3001.
6. Inputs to the linearizers vary from 0 to 5V.
