Abstract

A switch element includes a switch device having a drain, a source and a plurality of gates, and at least one additional interconnect located between the plurality of gates, the additional interconnect operative to establish a constant potential between the at least two gates.

Claims

1. A switch element, comprising:

a switch device having a drain, a source and a plurality of gates; and

at least one additional interconnect located between the plurality of gates, the additional interconnect operative to establish a constant potential between the plurality of gates.

2. The switch element of claim 1 further comprising at least three gates and at least two additional interconnects interleaved with the at least three gates.

3. The switch element of claim 1 wherein the plurality of gates are configured as ohmic contacts.

4. The switch element of claim 1 wherein the plurality of gates are configured as Schottky contacts.

5. The switch element of claim 1 wherein a pair of switch devices are coupled together.

6. The switch element of claim 1 wherein the at least one additional interconnect has a line width of approximately 0.5 μ

m.

7. The switch element of claim 1 wherein the at least one additional interconnect has a line width of approximately 0.5 μ

m and each of the plurality of gates has a line width of approximately 0.5 μ

m.

8. A portable transceiver having an antenna switch, comprising:

a transmitter operatively coupled to a receiver;

a switch device operatively coupled to the transmitter and to the receiver, the switch device having a drain, a source and a plurality of gates; and

at least one additional interconnect located between the plurality of gates, the additional interconnect operative to establish a constant potential between the plurality of gates.

9. The transceiver of claim 8 wherein the switch device further comprises at least three gates and at least two additional interconnects interleaved with the at least three gates.

10. The transceiver of claim 8 wherein the plurality of gates are configured as ohmic contacts.

11. The transceiver of claim 8 wherein the plurality of gates are configured as Schottky contacts.

12. The transceiver of claim 8 wherein a pair of switch devices are coupled together.

13. The transceiver of claim 8 wherein the at least one additional interconnect has a line width of approximately 0.5 μ

m.

14. The transceiver of claim 8 wherein the at least one additional interconnect has a line width of approximately 0.5 μ

m and in which each of the plurality of gates has a line width of approximately 0.5 μ

m.
