A technique for characterization and modeling of planar varactor diodes is presented. The diode structures were fabricated on a low cost GaAs process, measured in a shunt configuration, and subsequently modeled. The simulations are in good agreement with the measured data. The planar device was integrated in an MMIC VCO and the measured performance conforms to the design objectives.
