The companion ADL5240 integrates a gain block with DSA 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 …
