ADL5240 Datasheet 100 Mhz To 4000 Mhz Rf/if Digitally Controlled Vga

Manufacturer: Analog Devices

Overview: 100 MHz to 4000 MHz RF/IF Digitally Controlled VGA ADL5240.

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.
