In this paper the design of a VCO using GaInP/GaAs HBT technology is presented. The VCO is designed to be a part of a PDH point to point radio system. To achieve low phase noise performances GaInP/GaAs HBT technology and push-push topology have been chosen. The MMIC includes predistorters to emphasize the second harmonic, f/sub 0//2 prescalers for PLL locking and buffer amplifiers. A fully monolithic microstrip resonator is coupled with integrated varactors to achieve the specified tuning bandwidth. Phase noise, bandwidth and power measurements will also be presented.

Abstract
In this paper the design of a VCO using GaInP/GaAs HBT technology is presented. The VCO is designed to be a part of a PDH point to point radio system. To achieve low phase noise performances GaInP/GaAs HBT technology and push-push topology have been chosen. The MMIC includes predistorters to emphasize the second harmonic, f/sub 0//2 prescalers for PLL locking and buffer amplifiers. A fully monolithic microstrip resonator is coupled with integrated varactors to achieve the specified tuning bandwidth. Phase noise, bandwidth and power measurements will also be presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
