This paper presents a low noise first down-conversion mixer with a notch filter for the heterodyne receiver. The notch filter connected to the output node of the mixer driver stage plays a role of image rejection at an image frequency, thereby suppressing the sideband image noise and improving the m

## Abstract In this article, a ฮป/2 Uโshaped hairpin resonator was contained in a modified endโcoupled microstrip line. The increase of the sizes of Uโshaped hairpin resonator and modified endโcoupled microstrip line had no influence on the lower operating frequency and would shift the upper operati
