Abstract :
This paper deals with the design and experimental characterization of C-band microwave amplifier based on commercial SiGe hetero-junction bipolar transistor (HBT). In this design an impedance-matching technique that allows realization of the HBT amplifiers having a maximum gain within 4... 6 GHz frequency range is developed. As a result of this approach a low phase noise amplifier providing a 13 dB gain at 4.6 GHz and about 1 GHz bandwidth has been designed. In order to characterize a phase noise of the designed amplifier a phase noise measurement setup based on a carrier suppression technique was developed. A measured amplifier´s phase noise is proved to be lower than -160 dBc/Hz at 1 kHz Fourier frequency.
