Dual Matched Broadband RF DVGA 0.6GHz to 2.7GHz
F0443 Datasheet
Description
The F0443 is a highly integrated 0.6GHz to 2.7GHz dual channel RF digital variable gain amplifier designed for use in diversity/MIMO receivers. The F0443 provides two independent receiver paths each with 29.5dB typical maximum gain and 3.2dB NF at 2.5GHz.
For each path, gain control is split into four separate digital step attenuators: DSA0 provides 6dB of attenuation in a single step using SPI/I3C control. Its counterpart, DSA1, also provides 6dB of attenuation in a single step but it is programmed instead using an external direct control pin. DSA2 yields 29dB of SPI/I3C-controlled attenuation in 1dB steps,...
