Description 
M/A-COM's SA90-0001 is a Vector Modulator that signifi-
cantly reduces the required board space compared to hybrid 
solutions.  The monolithic passive elements will lead to 
greater repeatability lot-to-lot.  Low amplitude ripple will 
provide superior performance. High intercept and compres-
sion points will contribute to more linear system perform-
ance.  SA90-0001 is ideally suited for wireless infrastruc-
ture applications. 
M/A-COM’s MADRCC0002 Dual Linearizer is designed 
to simplify the control of Vector Modulators.  See  
Figure 1 and App Note AN3001.
