ADL5243 Datasheet 100 Mhz To 4000 Mhz Rf/if Digitally Controlled Vga

Manufacturer: Analog Devices

Overview: Data Sheet 100 MHz to 4000 MHz RF/IF Digitally Controlled VGA ADL5243.

General Description

The ADL5243 is a high performance, digitally controlled variable gain amplifier operating from 100 MHz to 4000 MHz.

The VGA integrates two high performance amplifiers and a digital step attenuator (DSA).

Amplifier 1 (AMP1) is an internally matched gain block amplifier with 20 dB gain, and Amplifier 2 (AMP2) is a broadband ¼ W driver amplifier that requires very few external tuning ponents.
