\begin{itemize}
\item Own simulations
\begin{itemize}
\item Better results to be expected (technology with higher $f_\text{t}$, $f_\text{max}$, stability not considered)
\item Maybe better results by using current mirrors to set operating points of buffer instead of resistors
\end{itemize}

\item General structure
\begin{itemize}
\item Removal of $g_\text{m}$ stage of Gilbert cell $\rightarrow$ more voltage headroom

\item Own simulations
\begin{itemize}
\item Better results to be expected (technology with higher $f_\text{t}$, $f_\text{max}$, stability not considered)
\item Further investigation needed to determine whether unusual LO power behavior is problematic
\item Maybe better results by using current mirrors to set operating points of buffer instead of resistors
\item Maybe better results by replacement of discrete component matching networks by transmission line based ones

\item Applications of this design
\begin{itemize}
\item SiGe HBT technology integrable with CMOS $\rightarrow$ scalable, suitable for mixed-signal ICs
