An RF front-end IC containing a low-noise amplifier and mixer is descr
ibed. On-chip temperature and supply-voltage compensation is used to s
tabilize circuit performance. Realized in a BiCMOS process, the circui
t 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 -10 dBm. The n-mixer input third-or
der intermodulation intercept is +6 dBm with 15.8 dB noise figure.
