A 1-GHz BiCMOS RF front-end IC

An RF front-end IC containing a low-noise amplifier and mixer is described. On-chip temperature and supply-voltage compensation is used to stabilize circuit performance. Realized in a BiCMOS process, the circuit consumes 13.0-mA total current from a 5-V supply. The amplifier gain at 900 MHz is 16 dB, the noise figure is 2.2 dB, and the input third-order intermodulation intercept is /spl minus/10 dBm. The mixer input third-order intermodulation intercept is +6 dBm with 15.8 dB noise figure.<
