    Low noise amplifier design using bjt in l band.

    Dear sir
    myself maulik patel research scholar want to design low noise amplifier design using bjt in l band. So please guide me how to setup the bias network, matching and all other design parameters in ads as well as its mathematical analysis.

    Re: Low noise amplifier design using bjt in l band.

    Most of the design comes from transistor actually. If you choose a good transistor with a relatively low noise you can figure out the rest from the datasheet. For L band i recommend SiGe:C transistors. They have pretty low Nose Figure around L band. From the datasheet you can decide on which Collector current=Ic and Collector Voltage=Vc you want to use. Depending on that you can Find your Base Current Ib from datasheets aswell.After that It is just like In electronic courses.Also add RF chokes where you don't want the RF to go.
