A 12.4–32 GHz CMOS Down-Conversion Mixer for 28 GHz 5G New Radio (NR)
Applied Sciences, 2023 We report a low voltage (VDD) and power (PDC) 12.4–32 GHz CMOS down-conversion mixer with high conversion gain (CG) for 28 GHz 5G communications. A quarter-wavelength (λ/4) transmission line (TL) and a coupling capacitor (Cc), named the λ/4-TL-C-based coupler, is proposed.
