  • Abstract
    Design concepts of fully monolithically integrated VCOs are presented that include special solutions for increasing the bandwidth of operation. Realised buffered VCO MMICs deliver RF power between 11.2 and 15.5 dBm over the frequency range from 4.6 to 6.1 GHz. The relative bandwidth ¿f/fm is more than 27%, which is one of the highest values ever achieved with MMIC-VCOs using diode tuning.
