摘要
Abstract
A Ka-band MMIC VCO was designed with 0.25 μm GaAs pHEMT process. The source electrode positive feed-back structure is adopted for VCO. The pHEMT whose source electrode and drain electrode are connected to the ground is used for the varactor. The resonance network and the matching network are optimized to improve the output power and the phase noise performance. The yield of the VCO is analyzed and improved by the Monte-Carlo method. The simulation data shows the typical output power of VCO is 10±1 dBm,the output frequency of VCO is 24.6~26.3 GHz,the harmonic suppression is better than 19 dB. The chip size of the MMIC VCO is 1.5 mm×1 mm.关键词
