ADL5240ACPZ-R7RF/IF射頻/中頻RFID的射頻放大器規(guī)格書PDF中文資料

ADL5240ACPZ-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ADL5240ACPZ-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(hào)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 ADL5240 is a high performance, digitally controlled variable gain amplifier (VGA) operating from 100 MHz to 4000 MHz. The VGA integrates a high performance, 20 dB gain, internally matched amplifier (AMP) with a 6-bit digital step attenuator (DSA) that has a gain control range of 31.5 dB in 0.5 dB steps with ±0.25 dB step accuracy. The attenuation of the DSA can be controlled using a serial or parallel interface.
