Abstract

This paper presents a compact 26/38GHz reconfigurable dual-band low-noise amplifier (LNA) for a narrow-LO dual-side mixing. By adopting a transformer-based pole-zero-inversion image-rejection technique, the LNA achieves 20dB and 19dB of gain, 3.5dB and 3.9dB noise figures at 26GHz and 38GHz, respectively. The image rejection ratios are better than 39dB and 41dB with an intermediate frequency of 6GHz.
