ABSTRACT: In this paper, we verify the potentiality of common-gate configuration as an active impedance matching to improve performance of PHEMT frequency multiplier by 4. A 8.87% relative bandwidth at millimeter wave frequencies for frequency multiplier by 4 is achieved by this technique. In this contribution, simulation results show the good impact of this technique on the performance of PHEMT frequency multiplier by 4 especially on the conversion gain and output power.
KEYWORDS: Active impedance matching stage, PHEMT technology, frequency multiplier, RF circuits, common-gate configuration, passive elements.
