W-band Multiplier/MPA
As the connection at 77GHz (between MMIC and external substrate) is critical, the transition
matching network is split into two parts: one on MMIC and one on the external substrate. The
following drawing gives the dimensions for a RO3003 substrate.
RO3003 thickness = 0.127 mm, εr=3.
