The wideband high-linearity mixers for a double conversion cable TV tuner is presented. The up-conversion mixer converts the input signal from 100MHz to 1000 MHz to the intermediate frequency (IF-) of 1 GHz above. And the down-conversion mixer converts the frequency back. The degeneration resistors are used to improve the linearity. The tuner is implemented in a 0.35μm SiGe technology. Input power at IdB compression point can reach +14.23dBm. The lowest noise figure is 17. 5dB. The two mixers consume 103mW under a supply voltage of 5 V.
