In a blender, puree the frozen raspberries and lemon lime soda until smooth.
Pour the raspberry puree into a punch bowl (or a large pitcher) and stir in the limeade concentrate. Then stir in the orange juice. If the punch is too tart, you can add some water.
Stir in the Champagne and the tequila. Serve immediately and garnish with fresh lime slices and/or raspberries.
