ADL5321ARKZ-R7屬于RF/IF射頻/中頻RFID的射頻放大器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADL5321ARKZ-R7射頻放大器在射頻應(yīng)用中，射頻放大器產(chǎn)品可用于信號增益和緩沖。這些產(chǎn)品與通用運(yùn)算放大器的不同之處在于，它們通常適用于更高的頻率，更傾向于提供不可調(diào)節(jié)的固定增益，并且輸入或輸出阻抗值符合常用傳輸線特性阻抗。

GENERAL DESCRIPTION

The ADL5321 incorporates a dynamically adjustable biasing circuit that allows for the customization of OIP3 and P1dB performance from 3.3 V to 5 V without the need for an external bias resistor. This feature gives the designer the ability to tailor driver amplifier performance to the specific needs of the design. This feature also creates the opportunity for dynamic biasing of the driver amplifier, where a variable supply is used to allow for full 5 V biasing under large signal conditions and then can reduce the supply voltage when signal levels are smaller and lower power consumption is desirable. This scalability reduces the need to evaluate and inventory multiple driver amplifiers for different output power requirements from 22 dBm to 26 dBm output power levels.
