Titel

Subharmonically injection locked 94 GHz MMIC HEMT oscillator using coplanar technology

Alternative
Subharmonisch synchronisierter 94 GHz MMIC HEMT Oszillator in koplanarer Schaltungstechnik
Abstract
A coplanar subharmonically injection locked VCO for 94 GHz with a tuning range of 4.5 GHz was developed, using 0.15 mu m AlGaAs/InGaAs/GaAs PM-HEMTs. A phase noise of -71 dBc/Hz at 1 MHz offset from the carrier was measured for the unlocked VC0. Using 3rd subharmonic injection locking, a phase noise of -106 dBc/Hz at 1 MHz offset (-91 dBc/Hz at 100 KHz offset) for the locked VCO with a locking range of 1 GHz was achieved.
