| Vector Modulator, 1.94 to 2.24 GHz V 4.00 SA90-0001 Features n n n n n n n CSP-6 Operates 1.94 to 2.24 GHz Chip Scale Package. Low Amplitude Ripple Linear Phase 50 Ohm nominal impedance Continuously Variable Across a Full 360 degree range Test Boards to be Available 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. See Figure 1 and App Note AN3001.
