As the connections at 77GHz (between MMIC and MMIC or between MMIC and
external substrate) are critical, the transition matching network is split into two
parts: one on MMIC and one on the external substrate. This choice allows doing
also a direct connection between MMICs. For a connection to an external
substrate a network is proposed on soft substrate for IN and OUT ports. The
following drawings give the dimensions for a RO3003 substrate
(thickness=0.127mm, εr=3).
