Hi Mateusz,
Gate input capacitance and output capacitance of any replacement transistor must be in the same neighborhood as the BS170. The closest match I’ve found is TN0110 which some here have been using with success. It’s a 100V device as opposed to BS170 which is a 60V device and provides better protection against high SWR voltages. The only thing to know is TN0110 must be installed with the flat side up to account for the reversed pinout.

Hi,
?
Would it be difficult to change BS170 final transistors to LDMOS ones??
?
