This module operates from 1.8 GHz - 3.9 GHz. It
features high gain and very low noise figure in the
receive mode and low insertion loss in the
transmission mode. The PIN switches provide high
power handling over 20 W CW signal. External SMT
components optimize the matching and enable
flexible frequency of operation.
