Abstract

A novel varactor tunable CPW (coplanar waveguide) slotline Gunn VCO (voltage-controlled oscillator) has been developed. The oscillator provides 16.3+or-0.45 dBm throughout a 300 MHz tuning range centered at 10.40 GHz. The signal quality and stability are very good throughout the tuning range. The circuit is small and lightweight, and offers low cost, good reproducibility, and excellent performance. The varactor tuning range should prove useful for frequency-modulated communication links, frequency-agile transmitters or local oscillators, and electronic warfare applications.<>
