摘要：It is disclod a microwave VCO implemented in planar way technique on the same standard glass reinforced FR4 substrate supporting the layout of the relevant control circuit (in particular, locking circuits and bias circuits) operating at a well lower frequency. The area occupied by the VCO on the standard glass reinforced FR4 substrate is very small, minimizing by this the power loss of the microwave oscillation during its propagation. To this purpo, the varactor is placed in clo contact with the active element (GaAsFET) of the VCO, which therefore does not include the traditional resonant cavity. The u of stubs in critical points of the circuit prevents the loss of power otherwi introduced by impedance mismatch. Through the measures, the VCO oscillation frequency can be driven up to 18 GHz, without altering by that the operation characteristics of the same at a significant extent. Moreover, since the Applicant has not recorded a significant electromagnetic interference in the substrate areas, clo to the VCO, it does not require as well appropriate shielding means. Thanks to the invention, it is thus possible to u the same manufacturing process to obtain both the VCO layout and the layout of the above mentioned low frequency.
