AD8333ACPZ-WPRF/IF射頻/中頻RFID的RF解調(diào)器規(guī)格書PDF中文資料

AD8333ACPZ-WP屬于RF/IF射頻/中頻RFID的RF解調(diào)器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD8333ACPZ-WPRF 解調(diào)器RF 解調(diào)器是設(shè)計用于從調(diào)制波中提取信號的器件，調(diào)制波則是通過使用頻率、幅度、相位、放大器或位移器而改變的波。

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.
