| Abstract: | This paper describes a low noise Broad band design of the amplifier and its applications at UHF band. This amplifier comprises three bipolar transistors ( 2 SC3358 ) mounted on a metallized dielectric plate in an enclosure ( 90 × 50 × 30mm3 ) . This amplifier have the following characteristics: frequency band 470-970MH2, gain>28dB, noise figure ( followed dy a mixer ) <1.5dB. |
