Patent ID: 7680464

Claim:
A radio frequency (RF) assembly for providing an RE signal path between first and second RF printed wiring boards (PWBs), the RF assembly comprising: a PWB frame having first and second opposing surfaces and having a portion of a waveguide formed therein, said waveguide portion having a first waveguide port at a first end thereof and having a second waveguide port at a second end thereof, said PWB frame configured to hold the first and second PWBs on the first surface thereof and to hold a third PWB on the second surface thereof such that when the third PWB is disposed on said PWB frame, the waveguide portion becomes a functional waveguide transmission line; a first waveguide feed disposed on the first PWB, such that when said first PWB is disposed on the first side of said PWB frame, said first waveguide feed is coupled to a first one of the first and second waveguide ports; and a second waveguide feed disposed on the second PWB such that when said second PWB is disposed on the first side of said PWB frame, said second waveguide feed coupled to a second one of the first and second waveguide ports.
