ADG919RF/IF射頻/中頻RFID的射頻開關規(guī)格書PDF中文資料

ADG919屬于RF/IF射頻/中頻RFID的射頻開關。由亞德諾半導體技術有限公司制造生產的ADG919射頻開關射頻開關產品是用于在多個可用信號路徑之間路由 RF、IF 或微波信號的器件。示例應用包括多天線（分集）接收器中的天線選擇、多模式系統中發(fā)射-接收路徑的選擇，或在發(fā)射和接收信號鏈之間切換天線。

GENERAL DESCRIPTION

The ADG918/ADG919 are wideband switches using a CMOS process to provide high isolation and low insertion loss to 1 GHz. The ADG918 is an absorptive (matched) switch having 50 Ω terminated shunt legs, whereas the ADG919 is a reflective switch. These devices are designed such that the isolation is high over the dc to 1 GHz frequency range. They have on-board CMOS control logic, thus eliminating the need for external controlling circuitry. The control inputs are both CMOS and LVTTL compatible. The low power consumption of these CMOS devices makes them ideally suited to wireless and general-purpose high frequency switching applications.
