ADG919BCPZ-REEL7屬于RF/IF射頻/中頻RFID的射頻開關(guān)。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的ADG919BCPZ-REEL7射頻開關(guān)射頻開關(guān)產(chǎn)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(tǒng)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.
