Amplifier for FM antennas

Image Number 2 for United States Patent #6653905.

An amplifier comprising a transformer and a plurality of FETs, for example, three FETs. An input terminal, which receives a signal from an FM antenna, is connected to one end of the primary winding of the transformer. A power-supply voltage is applied to one end of the secondary winding of the transformer. A given middle part of the secondary winding is connected to an output terminal. The transistors have their source connected in parallel to the other end of the primary winding of the transformer, their drains connected in parallel to the other end of the secondary winding, and their gates connected to the ground.
