The $${f_T}$$ of a BJT is related to its $${g_{m,}}\,\,{C_\pi }$$ and $${C_\mu }$$ as follows

$${f_T} = {{{C_\pi } + {C_\mu }} \over {{g_m}}}$$

$${f_T} = {{2\pi \left( {{C_\pi } + {C_\mu }} \right)} \over {{g_m}}}$$

$${f_T} = {{{g_m}} \over {{C_\pi } + C\mu }}$$

$${f_T} = {{{g_m}} \over {2\pi \left( {{C_\pi } + {C_\mu }} \right)}}$$
