System and method for attenuating and/or terminating RF circuit
A high-speed circuit assembly includes a high-speed circuit including at least one waveguide/transmission line, and a radiation absorbing material disposed in contact with or in close proximity with the waveguide/transmission line.
1. A test socket assembly comprising:
a frame assembly having a socket opening sized and configured to receive a device under test therein;
a high-speed circuit including a waveguide/transmission line extending to a waveguide/transmission line end, the high-speed circuit including a lead frame assembly disposed adjacent to the frame assembly, the waveguide/transmission line to carry a radio frequency signal including a high frequency signal and a substantially direct current signal; and
a radiation absorbing material in contact with or in close proximity with the waveguide/transmission line, the radiation absorbing material to attenuate or block the high frequency signal and allow the substantially direct current signal to pass in the waveguide/transmission line.
2. The test circuit assembly as recited in claim 1 , wherein the high-speed circuit includes at least one ring coupler.
3. The test circuit assembly as recited in claim 1 , wherein the radiation absorbing material absorbs signals having frequencies in centimeter-wave, millimeter-wave and sub-millimeter wave band.
