摘　　要：An up-conversion mixer implemented in a 0.35μm SiGe BiCMOS technology for a double conversion cable TV tuner is described, The mixer converts the 100MHz to 1000MHz band to the Intermediate Frequency of 1GHz above. The mixer meets the linearity and noise figure requirements for a TV tuner. The noise figure （IF） of 19.2-17.5dB, ldB compression of 12.1dBm, and gain of-1-0.7dB in the 900MHz band are achieved at a supply voltage of 5V. The power consumption is 47mW.
