Abstract :
A GaAs up converter integrated circuit used for a double conversion cable TV “set-top” tuner is described. The up converter IC converts the 50 to 550 MHz band to an IF of 700 MHz. The IC meets the linearity and noise figure requirements for a cable TV tuner. It includes an AGC and image reject filter. The reduced component count achieved by using an integrated circuit and the resulting reduction in the size of the tuner, provides potential cost savings over a discrete implementation
