Description
M/A-COM's SA90-0001 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 ripple will
provide superior performance. High intercept and compression points will contribute to more linear system performance. SA90-0001 is ideally suited for wireless infrastructure applications.
M/A-COM’s MADRCC0002 Dual Linearizer is designed
to simplify the control of Vector Modulators.
