Abstract :
A synthesizing method is proposed to design and implement wideband amplifiers in the microwave frequency range. The wideband amplifier is implemented by using Chebyshev matching transformers (CMT). In particular, the effective bandwidth of the CMT wideband amplifier increases 2.3GHz over the balance amplifier. The size of the CMT amplifier reduces to 30% of the balance amplifier. Two types of amplifier are built and tested. A methodology of designing the CMT amplifier is presented and implemented to validate this new method correct by measuring.
