Low cost high frequency device package and methods
View Patent ↗A low-cost high-frequency electronic device package and associated fabrication method are described wherein waveguide structures are formed from the high frequency device to the package lead transition. The package lead transition is optimized to take advantage of waveguide interconnect structure.
1. An electrical component package, comprising:
a package having a plurality of leads and a base;
a structure attached to said base, the structure having at least one site; and
at least one waveguide interconnect connecting the at least one site on said structure to at least one of said plurality of leads of the package, wherein the at least one lead attached to waveguide interconnect is tapered to minimize a shunt capacitance at an interface region between the waveguide interconnect and the at least one lead; and
wherein the structure has a second site; and wherein the at least one waveguide interconnect is internal to the package and connects the at least two sites on the structure to each other.
2. The package of claim 1 , wherein at least one lead adjacent the lead connected to the waveguide interconnect further comprises an electrical ground lead.
3. The package of claim 1 wherein two leads adjacent the lead connected to the waveguide interconnect each further comprises an electrical ground lead.
4. The package of claim 1 , wherein each waveguide interconnect further comprises a shield and wherein the shield has a connection to a ground of the structure.
5. The package of claim 1 , wherein each waveguide interconnect further comprises a shield and wherein the shield has a connection to a package lead ground.
6. The package of claim 1 , wherein each waveguide interconnect further comprises a shield and wherein the shield has a connection to a package lead ground and a ground of the structure.
7. The package of claim 1 , wherein an impedance of the at least one lead is matched to the impedance of the waveguide interconnect.
8. The package of claim 7 , wherein the waveguide interconnect impedance is matched to the an impedance of the structure.
9. The package of claim 1 further comprising:
a second structure attached to said base, the structure having at least one site; and
at least one waveguide interconnect connecting the at least one site on the structure attached to said base to the at least one site on a second structure attached to said base.
10. The package of claim 1 , wherein each site further comprises a bonding pad.
11. The package of claim 1 , wherein each site further comprises a bonding pad.
