AD8333ACPZ-WPRF/IF射频/中频RFID的RF解调器规格书PDF中文资料

AD8333ACPZ-WP属于RF/IF射频/中频RFID的RF解调器。由亚德诺半导体技术有限公司制造生产的AD8333ACPZ-WPRF 解调器RF 解调器是设计用于从调制波中提取信号的器件，调制波则是通过使用频率、幅度、相位、放大器或位移器而改变的波。

GENERAL DESCRIPTION

The AD8333 is a dual-phase shifter and I/Q demodulator that enables coherent summing and phase alignment of multiple analog data channels. It is the first solid-state device suitable for beamformer circuits, such as those used in high performance medical ultrasound equipment featuring CW Doppler. The RF

inputs interface directly with the outputs of the dual-channel, low noise preamplifiers included in the AD8332.
