In this paper, two types of MMIC voltage controlled oscillators have been successfully demonstrated. The first chip with single tuning diode shows the excellent tuning linearity. The second chip with two tuning diodes can improve the tuning bandwidth. The measured results of VCO with single diode shows the tuning bandwidth of 800 MHz centered at 9.2 GHz with the output power of 12 dBm. The second VCO with dual tuning diodes shows the tuning bandwidth of 2 GHz centered at 9.4 GHz The VCOs are fabricated with Hughes 0.5 micron ion implant MESFET foundry process[l].
