We have fabricated all-high {ital T}{sub {ital c}} superconducting tunnel junctions in the material Ba{sub 1{minus}{ital x}}K{sub {ital x}}BiO{sub 3}. The junctions are of very high quality and have a Josephson supercurrent. For the low-resistance junctions, the {ital I}{sub {ital c}R} product approaches the theoretical limit.
