Electronic components with reactive filters

An electronic component, comprising:

• a half bridge adapted for operation with an electrical load having an operating frequency, the half bridge comprising a first switch and a second switch each having a switching frequency, the first switch and the second switch each including a first terminal, a second terminal, and a control terminal, wherein the first terminal of the first switch and the second terminal of the second switch are both electrically connected to a node;
• and
• a filter, a first terminal of the filter being electrically coupled to the node;
• wherein
• the first switch or the second switch comprises a high-voltage depletion-mode transistor and a low-voltage enhancement-mode transistor, the high-voltage depletion-mode transistor comprising a source electrode, and the low-voltage enhancement-mode transistor being mounted directly on top of the source electrode of the high-voltage depletion-mode transistor;
• and
• the half bridge and the filter form a module, and a volume of the module divided by a maximum output power of the electronic component is less than 6 cm3/Watt.
