Product Overview
The AM1146 is a broadband digitally controlled variable gain amplifier that covers the 2-18 GHz frequency range. It provides 2dB of gain variation with approximately equal steps of 0.6dB. Output IP3, P1dB, and noise figure are decoupled from the gain variation, so the AM1146 provides consistent noise figure and nonlinear performance for any gain state. The device is packaged in a 3mm QFN with internal 50Ω matching which makes the AM1146 ideal for demanding, low SWaP applications.
