A broadband monolithic transformer balun has been designed and fabricated at millimeter-wave frequencies. The balun is implemented on 0.13 um CMOS process and integrated with the 60 GHz mixer circuit. A measured amplitude and phase balance less than 3dB and 5 degrees respectively over the 50-65 GHz frequency band was achieved. The designed device has advantages of small size, simple layout and wide operational frequency range. © 2007 IEEE.
