I am trying to implement a multiple antenna (16 channels) beamforming
system with 2.6GHz carrier freq. To capture the phase difference between
channels, I need to downconvert the 2.6GHz RF to complex baseband using
some I/Q mixers. I found out (from Marki) that a 2.6GHz I/Q mixer costs
over $150, which is way above my budget limit... I wonder if there is any
trick to avoid having mulitple mixers for such case?
