초록

In this paper, We have designed and fabricated VCO in two way, the common source and common gate circuit for I local oscillator of 60 GHz wireless LAN system. The VCO employed a GaAs MESFET for negative resistance and a varactor diode for frequency tuning. The common gate VCO was measured the phase noise -112 dBc/Hz at the 1 MHz frequency offset. The output power and the second harmonic frequency suppression were 7.81 dBm and -29.3 dBc when tuning voltage was 3V, respectively. The total size of VCO was 28.6$\times$12.14 $\textrm{mm}^2$.
