Abstract

We designed and implemented the RFIC(RF front-end IC) for DTV(Digital TV) tuner. The DTV tuner RF front-end consists of low noise IF amplifier fur the amplification of 900 MHz RF signal and down conversion mixer for the RF signal to 44MHz IF conversion. The RFIC is implemented on ETRI 0.8u high resistive (2㎘ -cm) and evaluated by on wafer, packaged chip test. The gain and IIP3 of IF amplifier are 15㏈ and -6.6㏈m respectively. For the down conversion mixer gain and IIP3 are 13㏈ and -6.5㏈m. Operating voltage of the IF amplifier and the down mixer is 5V, current consumption are 13㎃ and 26㎃ respectively.
