A microwave module lid is disclosed. The microwave module lid can include an inner side operable to define, at least in part, a cavity configured to have a radio frequency (RF) emitting component disposed therein. The microwave module lid can also include two or more dielectric layers proximate one another. Each layer can have a thickness, a dielectric constant, and a dielectric loss characteristic. In addition, the microwave module lid can include a metal backing layer proximate one of the dielectric layers to contain RF energy within the lid. The thicknesses, the dielectric constants, and/or the dielectric loss characteristics of the dielectric layers can be configured to minimize RF resonance in the cavity. |

1. A microwave module lid, comprising:
an inner side operable to define, at least in part, a cavity configured to have a radio frequency (RF) emitting component disposed therein; at least two dielectric layers proximate one another, each layer having a thickness, a dielectric constant, and a dielectric loss characteristic; and a metal backing layer proximate one of the dielectric layers to contain RF energy within the microwave module lid, wherein the thicknesses, the dielectric constants, the dielectric loss characteristics, or combinations thereof of the at least two dielectric layers are configured to minimize RF resonance in the cavity. |
