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, 1dB 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. 收起
