About SMA-3.5mm-2.92mmK and 1.85mmV-2.4mm connection

While SMA connectors can be mechanically connected to 3.5mm and 2.92mmK connectors, reflection occurs on the connected surfaces due to the different sizes of the external and central conductors.
While 1.85mm connectors can be mechanically connected to 2.4mm connectors, reflection occurs on the connected surfaces due to the different sizes of the external and central conductors.
