A low cost solution employing harmonic oscillation to the frequency synthesizer at 5.8 ㎓ is proposed. The proposed frequency synthesizer is composed of 2.9 ㎓ PLL chip, 2.9 ㎓ oscillator, and 5.8 ㎓ buffer amplifier The measured data shows a frequency Outing range of 290 ㎒, ranging from 5.65 to 5.94 ㎓ about 0.5 ㏈m of output power, and a phase noise of -107.67 ㏈c/㎐ at the 100 ㎑ offset frequency. All spurious signals including fundamental oscillation power(2.9 ㎓) are suppressed at least 15 ㏈c than the desired second harmonic signal.
