Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
A microwave device for heating materials, said device comprising: a. a tray structure; b. said tray structure being flattened and rectangularly spa shaped and having a top wall; c. said top wall having a plurality of apertures; d. a solid state module disposed in each of said apertures, each of said solid state modules functioning as a microwave oscillator; e. leads extending from opposite sides of each of said modules and physically connected to walls forming the outline of each of said apertures for supporting said modules in said tray structure; f. a pair of input terminals extending into said tray structure for series connection to said solid state modules; and g. whereby said tray structure may be utilized in conjunction with a conventional oven to provide it with a microwave heating capability.
