Fully integrated differential 24 GHz receiver using a 0.8 /spl mu/m SiGe HBT technology

In this paper, the authors demonstrate a fully integrated, differential 24 GHz receiver using a commercially available 0.8 /spl mu/m Si/SiGe HBT technology. The integrated components are a low-noise amplifier, voltage-controlled oscillator, buffer, down-converter quadrature mixer and 16:1 static frequency divider. The conversion gain was measured to be 33 dB for an intermediate frequency of 200 MHz with an input compression point of -27 dBm. Special emphasis has been placed on the electrical isolation of function blocks on-chip.
