The kit includes a single sided PCB on which is already mounted the PA transistor, there is a suitable heat sink on which to mount the PCB with the provided screws. All electronic components are included as are 2 SMA sockets. Assembly of the kits will require some surface mount components to be soldered to the PCB.
