Abstract :
Conventional Weaver receivers select the signal channel and reject the image. This paper offers a simple method making it possible to select either signal or image by a single LO frequency. As a result, the number of LO frequency locations can be reduced by half, thereby relaxing the RF integer-N PLL frequency synthesizer requirements.
