Latest Patents
Varallo's latest patents include a high voltage, high frequency amplifier circuit and a high voltage, high frequency amplifier employing power transistors. The first patent describes an amplifier that provides parallel AC signal amplification paths through each transistor while maintaining a single DC power path through the transistors in series. In this design, two FETs have their gate electrodes connected to an input terminal and their drain electrodes connected to an output terminal, allowing for two parallel AC amplifying paths while blocking DC current flow. The drain electrode of the first FET is connected through an RF choke to a source of DC operating potential, and its source electrode is connected through an RF choke to the drain electrode of the second FET. The source electrode of the second FET is connected to ground through a zener diode, creating a single DC conductive path between the source of operating potential and ground through the two FETs in series.
The second patent also focuses on a high frequency amplifier that employs power transistors. Similar to the first, this amplifier provides parallel AC signal amplification paths through each transistor and a single DC power path through the transistors in series. In this embodiment, the source electrodes of the two FETs are connected to an input terminal, while their drain electrodes are connected to an output terminal. The drain electrode of the first FET is connected through an RF choke to a source of DC operating potential, and its source electrode is connected through an RF choke to the drain electrode of the second FET. The gate electrode of the second FET is connected to ground, ensuring a single DC conductive path between the source of operating potential and ground through the two FETs in series.
