چکیده
This paper presents a broadband frequency quadrupler (FQ) implemented with standard 130-nm SiGe BiCMOS process. Two push-push doublers (×2) operate at an input of 32.5–55 GHz and 65–110 GHz, respectively. To properly drive the two enough power bandwidth, transformer coupled amplifiers (PAs) have been adopted. The former amplifier is based on neutralized capacitor structure latter topology. A nonlinear device model systematic methodology to generate maximum second harmonic are proposed. By manipulating nonlinearity optimizing magnetically capacitively resonator (MCCR) matching networks, optimum conditions for generation provided. measurement results show that proposed provides 90-GHz bandwidth 80-dB dynamic range high energy efficiency η 3.7% 210 GHz.
