Abstract :
This paper described the design of a broadband LNA for TV tuner. The LNA uses two stage structures to achieve trade off of output impedance match and gain. In order to reduce the NF of the amplifier, noise canceling principle is adopted to cancel the noise. The simulation result shows that, in operation bandwidth 48 MHz~860 MHz, the gain is 24 dB, Noise figure is 3 dB, input impedance and output impedance match are also good.
