Abstract
An image trap filter disposed between the low noise amplifier and the mixer of a radio frequency receiver that overcomes the adverse effect of process variations on image signal rejection for both a single-band radio frequency receiver and a multi-band radio frequency receiver by setting the image trap filter response at the center of the band of interest at production test. The image signal problem is presented at the input of the radio frequency receiver and the image trap filter is adjusted for the desired frequency response.
