Abstract
A 52.5GHz-66GHz frequency tripler using $0.13\mu\mathrm{m}$ SiGe HBT process is presented, which adopts a single balanced structure, with a high conversion gain up to 14.3dB. A maximum saturated output power $(\mathrm{P}_{\text{sat}})$ up to 12.3dBm@57GHz is measured, with a 3-dB bandwidth of 13.5GHz (22.7% relative bandwidth). A folded marchand balun is applied to transform single-end signals into differential ones, with an amplitude difference less than 0.5dB and a phase difference within $180\pm 6$ degrees. A gain enhancing technique is also adopted. The chip size is $620\mu\mathrm{m}\times 200\mu\mathrm{m}$ without pads and $880\mu\mathrm{m}\times520\mu\mathrm{m}$ altogether.
