AD8340ACPZ-WPRF/IF射頻/中頻RFID的RF調制器規(guī)格書PDF中文資料

AD8340ACPZ-WP屬于RF/IF射頻/中頻RFID的RF調制器。由亞德諾半導體技術有限公司制造生產的AD8340ACPZ-WPRF 調制器射頻 (RF) 調制器產品用于通過更改載波的幅度、相位和/或頻率，將信息編碼到正弦載波信號上。執(zhí)行反向解調操作的接收設備會選擇性地以所需載波頻率接收傳入信號，從而將載波屬性的變化轉換回原始形式。這樣的配置允許使用通信通道來同時傳輸多條消息，而彼此之間沒有干擾。

GENERAL DESCRIPTION

The AD8340 vector modulator performs arbitrary amplitude and phase modulation of an RF signal. Because the RF signal path is linear, the original modulation is preserved. This part can be used as a general-purpose RF modulator, a variable attenuator/phase shifter, or a remodulator. The amplitude can be controlled from a maximum of ?2 dB to less than ?32 dB, and the phase can be shifted continuously over the entire 360° range. For maximum gain, the AD8340 delivers an OP1dB of 11 dBm, an OIP3 of 24 dBm, and an output noise floor of ?149 dBm/Hz, independent of phase. It operates over a frequency range of 700 MHz to 1.0 GHz.
