A low-power    $W$   -band (75&#x2013;110 GHz) double-balanced up-conversion mixer using a 0.13    $\mu$   m SiGe:C BiCMOS technology with    $f_\mathrm{T}/f_\mathrm{max}=250/370~\mathrm{GHz}$    is presented. The mixer includes on-chip transformer baluns at the LO and RF ports for on-wafer characterization. At 91.3 GHz, the active mixer achieves a single sideband (SSB) power conversion gain of 4.1 dB with a 3-dB RF bandwidth (BW) of 30 GHz from 78.1 to 108.3 GHz, covering almost the entire    $W$   -band. The linearity performance, characterized by    $\mathrm{OP}_{1\mathrm{dB}}$    and    $P_{\mathrm{sat}}$   , is 0.6 and 1.8 dBm, respectively while consuming only 11 mW from a 1.8 V supply. Moreover, a second-order IF    $LC$    low-pass filter (LPF) with a cutoff frequency of 1.4 GHz is integrated to provide an additional spurious suppression of    $\sim$   12 and    $\sim$   19 dB at the second and third harmonic of the fundamental IF (i.e., 1.25 GHz). The overall chip area, including the IF LPF is 990    $\times$    540    $\mu$   m (0.53 mm   $^2$   ). To the best of authors&#x2019; knowledge, the active up-conversion mixer achieves the lowest power consumption along with the highest    $\mathrm{OP}_{1\mathrm{dB}}$   /   $P_{\mathrm{sat}}$    and 3-dB RF BW reported among all prior published    $W$   -band SiGe-HBT up-conversion mixers.
