Provided is a terrestrial-digital multimedia broadcasting (T-DMB) and digital audio broadcasting (DAB) low intermediate frequency (IF) receiver. A T-DMB and DAB low IF receiver comprises a low noise amplifier (LNA) 202, an image rejection down-conversion mixer 203, a low pass filter 204, an amplifier 205, a local oscillator 208, and a phase-locked loop 209. Particularly, the LNA, the image rejection down-conversion mixer, the low pass filter, the amplifier, the local oscillator, and the phase-locked loop are integrated in a monolithic semiconductor integrated circuit substrate. Using the T-DMB and DAB low IF receiver allows a removal of a conventional SAW filter and the T-DMB and DAB low IF receiver can be easily integrated in the monolithic semiconductor integrated circuit substrate, and manufactured at low costs.
