Abstract

In this paper, it is designed for 5.8GHz Wireless LAN sub harmonic resistive mixer. Sub harmonic resistive mixer is constituted by advantage of sub harmonic mixer and resistive mixer. Sub harmonic resistive mixers mix harmonics of LO with RF and obtain IF frequency. Therefore, it was possible to use decreasing LO frequency than conventional mixers. And, Sub harmonic resistive mixer has low IMD because of using unbiased channel resistance of GaAs FET. When LO power is 13dBm, the conversion loss of manufactured sub harmonic resistive mixer is 10.67 dB. And IIP3 of mixer is 21.5dBm.
