Abstract:
The planar Balun of the present invention can be used in various hundred to and thousand-watt level push-pull power amplifiers, which can greatly reduce the area and the amount of second harmonics of the power amplifier, and improve the flexibility of circuit layout and spectral purity, especially at high frequencies, such as around 915 MHz, and can replace the widely used coaxial Balun to simplify amplifier design.
