Matched 50 Ω input stage
3.3 V to 5 V single supply
32-lead, 5 mm × 5 mm LFCSP package The ADL5246 is a high performance, low noise variable gain
amplifier (VGA) optimized for multistandard base station receivers
and point to point receive (Rx) and transmit (Tx) applications. The
low noise figure and excellent linearity performance allow the
device to be used in a variety of applications.
The device consists of a low noise amplifier, a high linearity
VGA, and a ½ W output driver stage. The variable attenuator
networks are optimized to provide high linearity performance
over the 45 dB gain control range. Gain is set using a unipolar
control voltage from 0 V to 3.3 V. The output stage of the ADL5246 …
