Transmit/Receive Modules

Science is a way to teach how something gets known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, from show …

Richard Feynman (1918–1988)

In Chapter 1 we deduced that many important array parameters are defined by the front-end subsystems: the antennas, polarizers, T/R modules, and beamformers. While microstrip/printed board antennas and beamformers can be relatively inexpensive, T/R modules constitute 50% of the overall array cost and 40% and 10% of the costs are apportioned to subarray manufacturing and array integration, ...
