Abstract

A compact frequency octupler designed for upper and lower E-band transceivers is implemented in IBM 0.13μm SiGe technology. Three frequency doubler stages are used with harmonic rejection conducted at the first two doublers for wide band spectral purity. With a 0 dBm input power, the frequency octupler reaches above 7.5 dBm output power between 56 GHz to 84 GHz with a peak output power of 13.5 dBm. All even harmonics: 2nd, 4th, 6th, 10th, are suppressed by more than 40 dBc across the frequency band. Moreover, the 6th and 10th harmonics are suppressed by over 40 dBc at temperatures between-40°C to 85°C. The circuit enables an extra input option of a frequency quadrupler and occupies 1.23×1.1 mm2 and consumes 152 mA from a 2.7 V supply.
