Abstract :
This paper describes a 48-860 MHz TV splitter amplifier with three outputs, based on a negative feedback design. The amplifier is intended for TV, VCR and set-top box (STB) applications, where multiple tuners have to be connected to the same cable outlet. The amplifier compromises high linearity and low noise figure by controlling its gain. At a frequency of 850 MHz, the input IP2 and IP3 are 94 dBmV and 73 dBmV, respectively, for the lowest gain setting while the noise figure is 7 dB for the highest gain setting. The design is fabricated in a 0.5 μm, 30 GHz BiCMOS technology and dissipates 130 mW from a 3.3 V supply.
