Abstract
A hermetically sealed housing (10) includes a dielectric end portion (118) which provides a transmission-line feedthrough between a printed-circuit such as HDI and exterior connections. A first transmission line (1) on the PC board (30) transitions to a 3-via transmission line (4), which transitions to a third coplanar, microstrip, or stripline transmission line (3). The third transmission line (3) transitions to a second 3-via transmission line (5), which ends at a coplanar transmission line (2) which is outside the housing.
