W-band Multiplier/MPA
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 to do,
for OUT2 port, a direct connection between MMICs. For a connection to an
external substrate a network is proposed on soft substrate for OUT1 and OUT2
ports. The following drawings gives the dimensions for a DUROID substrate
(thickness=0.127mm, εr=2.2).
