rf low noise amplifier design
i need some help in how to design low noise amplifier for RF. anybody who have idea please help me
Select a amplifying device with a very low noise figure. See what the source impedance requirement is to obtain this noise figure. Bias the device at the required Ic or Id and provide input matching between your source, and what the device input wants to see. Follow up with a optimal gain stage. First stage will set the overall noise figure of your amplifier. Investigate the stability factor of your design and make sure it is at least 1.2 over the whole operating range. If under 1 try and compensate or use another device.
Read a good basic RF amplifier design book
