A DC-100 GHz Frequency Doubler in InP DHBT Technology
Résumé
A broad-band monolithic integrated active frequency doubler operating in DC-100 GHz frequency range is presented. The circuit is fabricated in a self-aligned InP DHBT process. Circuit measurements show sinusoidal output waveform at 100 GHz with a rms time jitter of 400 fs. The doubler has a maximum conversion gain of +1 dB at 60 GHz. The fundamental suppression is better than 24 dB in the whole frequency range.
