The authors have demonstrated a fully integrated receive frontend addressing the ISM-Band at 24GHz utilizing a standard SiGe HBT MMIC process with a relaxed emitter scaling of 1.2 pm, for the first time. Extremely compact circuit design and layout techniques are applied to a mature Si/SiGe technology, resulting in a low-cost integrated circuit enabling consumer-oriented systems at Ka band. The integrated components are a preamplifier, a mixer with an IF buffer and a local oscillator. The conversion gain is determined to be 16.3 dB for an intermediate frequency of 100 MHz.

Abstract-This paper describes the wafer level integration of a differential 24 GHz SiGe-MMIC oscillator including a buffer amplifier with a differentially driven patch antenna. The patch antenna is realized on 30 µm BCB (Benzo Cyclo Butene) used as a dielectric layer. The radiated power of the patch antenna driven by the oscillator is calculated based on measurements and the result is discussed.
