7.2.3 Other Applications

The LMH6574 could support a multi antenna receiver with up to four separate antennas. Monitoring the signal strength of all 4 antennas and connecting the strongest signal to the final IF stage would provide effective spacial diversity.

For direction finding, the LMH6574 could be used to provide high speed sampling of four separate antennas to a single DSP which would use the information to calculate the direction of the received signal.
