60GHz LNA and 15GHz VCO Design for Use in Broadband Millimeter-Wave WPAN System

This paper presents a 60 GHz LNA and a 15 GHz VCO with wide frequency range for Millimeter WPAN operating from 57-64 GHz. Using a cost-effective SiGe BiCMOS technology with ft and fmax of 200 GHz and 300 GHz respectively, the LNA demonstrates good matching and a gain of more than 20 dB with excellent flatness (less than 1.2 dB) from SSGHz to 65 GHz. The 15 GHz VCO, which is used to generate the 60 GHz LO signal, exhibits high output power of above 2 dBm with tuning range of 20%. This translates to a frequency range of 53 GHz to 66 GHz.
