The companion ADL5243 integrates a ¼ W driver amplifier to
the output of the gain block and DSA 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. …
