ADRF6820ACPZ-R7屬于RF/IF射頻/中頻RFID的RF解調(diào)器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADRF6820ACPZ-R7RF 解調(diào)器RF 解調(diào)器是設(shè)計(jì)用于從調(diào)制波中提取信號(hào)的器件，調(diào)制波則是通過(guò)使用頻率、幅度、相位、放大器或位移器而改變的波。

GENERAL DESCRIPTION

The ADRF6820 is a highly integrated demodulator and synthesizer ideally suited for next generation communication systems. The feature rich device consists of a high linearity broadband I/Q demodulator, an integrated fractional-N phase-locked loop (PLL), and a low phase noise multicore, voltage controlled oscillator (VCO). The ADRF6820 also integrates a 2:1 RF switch, an on-chip tunable RF balun, a programmable RF attenuator, and two low dropout (LDO) regulators. This highly integrated device fits within a small 6 mm × 6 mm footprint.
