The present invention generally relates to extrusion-resistant seals for an expandable tubular assembly. In one aspect, a seal assembly for creating a seal between a first tubular and a second tubular is provided. The seal assembly includes an annular member attached to the first tubular, the annular member having a groove formed on an outer surface of the annular member. The seal assembly further includes a seal member disposed in the groove, the seal member having one or more anti-extrusion bands. The seal member is configured to be expandable radially outward into contact with an inner wall of the second tubular by the application of an outwardly directed force supplied to an inner surface of the annular member. Additionally, the seal assembly includes a gap defined between the seal member and a side of the groove. In another aspect, a method of creating a seal between a first tubular and a second tubular is provided.

A distributed cell field-effect transistor (FET) amplifier (40) includes a plurality of parallel, elongated source (46a) and drain (46b) regions of individual FET unit cells (46) formed in a substrate (42) in transverse alternating relation, with a plurality of elongated channel regions (46c) being formed between and parallel to adjacent source (46a) and drain (46b) regions respectively. A source foot (48) and a drain foot (50) extend perpendicular to the source (46a) and drain (46b) regions on opposite longitudinally spaced sides thereof respectively. A gate foot (52) extends parallel to the source (48) and drain (50) feet, between the source foot (48) and the cells (46). Source (54) and drain (56) pads and gate (58) fingers extend from the source (48), drain (50) and gate (52) feet into electrical connection with the respective source (46a), drain (46b) and gate ( 46c) regions respectively. The source pads (54) include airbridge portions (54b) which extend over the gate foot (52) without making contact therewith. A fixed tuning circuit (70) is connected between the gate foot (52) and source foot (48), including an inductive stub (72) having a first end connected to the gate foot (52) and a second end, and a capacitor (74) having a first plate (74a) which is integral with the source foot (48) and a second plate connected to the second end of the stub (72).
