This paper presents a 2.4 GHz vector modulator fabricated on mechanically flexible, low-cost, environmentally friendly, celluose-based substrate. This circuit can be adopted either as a digitally controlled target for radars' testing, or, more in general, as an I/Q modulator in RF systems. The system is composed by a directional coupler, two mixers and a Wilkinson divider, all of them designed in...
The design of complex RF devices such as oscillators, amplifiers and mixers requires accurate CAD simulations. Usually these devices are designed by using the “Harmonic Balance” frequency domain technique that calculates the magnitude and phase of voltages (or currents) in a non-linear circuit. The passive part of the sub-system (matching circuits, filters, feeding networks) is simulated exploiting...
