PLL 34 GHz

A completely integrated single-chip phase locked loop based on a 0.2 mu m gate length enhancement / depletion AlGaAs/GaAs/ AlGaAs-HEMT technology has been designed and characterized. The chip contains a VCO with 34 GHz center frequency, a dynamic frequency divider by two, a static divider by eight, a phase detector. and a loop fitter.. The chip size is 2.0 x 1.5 mm2. The power consumption is 1.2 W at a supply voltage of -5.0 V. The locking range is approximately +- 700 MHz. The phase noise of locked PLL is -83 dBc/Hz at 100 kHz and -102 dBc/Hz at 1 MHz offset from the carrier frequency, respectively.
