Abstract
A high output power amplifier with change of voltage transformation ratio of a transformer is disclosed. The high output power amplifier using a transformer installed to output leads thereof, which can increase dynamic range and efficiency thereof as voltage transformation ratio of the transformer is adjusted and load resistance is adjusted so as not to generate signal distortion phenomenon and not to decrease its efficiency.
Claims3
A high output power amplifier with change of voltage transformation ratio of a transformer comprising:
- amplifiers which are formed in pairs to correspond to power transistors, such that power transistors receive differential input signals, respectively, to perform a differential operation;
- capacitors which are located between output leads of the power transistors;
- and
- a transformer whose primary nodes are connected to the output leads of the amplifiers, respectively, and whose secondary nodes are used as output leads.
