Signal amplifiers having plated aluminum housing bodies with a back plate permanently attached thereto
View Patent ↗Signal amplifiers are provided that have a two (or more) piece housing that has an input port, an output port and a power port. At least one of the housing pieces comprises an aluminum housing piece. A first coaxial connector is mounted in the input port, a second coaxial connector is mounted in the output port and a third coaxial connector is mounted in the power port. A power amplifier is mounted within the housing, and is configured to amplify an input signal received through the first coaxial connector. At least first and second of the housing pieces have at least one metal plated thereon, and the first housing piece is soldered, welded or brazed to the second housing piece.
1. A signal amplifier, comprising
a housing that includes a first aluminum housing piece and a second housing piece, the housing including an input port, an output port and a power port;
a first coaxial connector mounted in the input port;
a second coaxial connector mounted in the output port;
a third coaxial connector mounted in the power port;
a power amplifier mounted within the housing that is configured to amplify an input signal received through the first coaxial connector;
wherein at least a portion of the first aluminum housing piece and at least a portion of the second housing piece have at least one metal plated thereon, and
wherein the first aluminum housing piece is permanently attached to the second housing piece by soldering, welding or brazing,
wherein the at least one metal plated on the housing comprises copper that is flash coated onto the first and second housing pieces.
2. The signal amplifier of claim 1 , wherein the first, second and third coaxial connectors each comprise female F-style coaxial connectors having brass connector housings.
3. The signal amplifier of claim 1 , wherein the second housing piece comprises an aluminum back plate.
4. The signal amplifier of claim 1 , wherein the second housing piece comprises a steel back plate.
5. The signal amplifier of claim 1 , wherein the second housing piece comprises a brass back plate.
6. The signal amplifier of claim 1 , wherein the at least one metal plated on the housing further comprises a nickel-based layer that is plated on the copper flash coat.
7. The signal amplifier of claim 1 , wherein the at least one metal plated on the housing further comprises a tin-based layer that is plated on the copper flash coat.
8. The signal amplifier of claim 1 , wherein the at least one metal plated on the housing further comprises a nickel-based plating layer and a tin-based plating layer that are plated on the copper flash coat.
9. The signal amplifier of claim 1 , wherein the at least one metal plated on the housing further comprises a nickel-tin-based alloy plating layer that is plated on the copper flash coat.
10. The signal amplifier of claim 1 , wherein the first aluminum housing piece comprises a housing body and the second housing piece comprises an aluminum back plate, and wherein the housing body is mounted directly to the back plate without an intervening gasket.
11. The signal amplifier of claim 1 , wherein the first aluminum housing piece is permanently attached to the second housing piece by soldering, and wherein the solder used to solder the first aluminum housing piece to the second housing piece comprises a lead-based solder.
12. The signal amplifier of claim 1 , wherein the first aluminum housing piece is permanently attached to the second housing piece by soldering, and wherein the solder used to solder the first aluminum housing piece to the second housing piece comprises a non-lead-based solder.
13. The signal amplifier of claim 1 , wherein the portions of the first housing piece and the second housing piece that are soldered together comprise portions of the first and second housing pieces that have the least one metal plated thereon.
14. A signal amplifier, comprising
a housing that includes a first aluminum housing piece and a second housing piece, the housing including an input port, an output port and a power port;
a first coaxial connector mounted in the input port;
a second coaxial connector mounted in the output port;
a third coaxial connector mounted in the power port;
a power amplifier mounted within the housing that is configured to amplify an input signal received through the first coaxial connector;
wherein at least a portion of the first aluminum housing piece and at least a portion of the second housing piece have at least one metal plated thereon, and
wherein the first aluminum housing piece is permanently attached to the second housing piece by soldering, welding or brazing,
wherein the at least one metal plated on the housing comprises electroless nickel that is coated onto the first and second housing pieces.
15. The signal amplifier of claim 14 , wherein the at least one metal plated on the housing further comprises a tin-based layer that is plated on the electroless nickel coat.
16. The signal amplifier of claim 14 , wherein the at least one metal plated on the housing further comprises a nickel-tin-based alloy plating layer that is plated on the electroless nickel coat.
