VCA5807EVM

评估模块, 用于VCA5807 集成电压控制放大器, 无源CW混频器

The is an evaluation module for the VCA5807 device. The VCA5807 is an integrated voltage controlled amplifierVCA solution specifically designed for ultrasound systems in which high performance and small size are required. The VCA5807 integrates a complete time gain controlTGC imaging path and a continuous wave dopplerCWD path. It also enables users to select one of various power/noise combinations to optimize system performance. Therefore, the VCA5807 is a suitable ultrasound analog front end solution not only for high end systems but also for portable systems. The VCA5807 integrates a low power passive mixer and a low noise summing amplifier to accomplish onchip CWD beamformer. 16 selectable phase delays can be applied to each analog input signal. Meanwhile a unique 3rd and 5th order harmonic suppression filter is implemented to enhance CW sensitivity.
