NSE–6
System Module

RF Module

This RF module takes care of all RF functions of the engine. RF circuitry
is located on one side (B–side) of the 6 layer PCB. PCB area for the RF
circuitry is about 40 x 50 mm.
EMC leakage is prevented by using a metal B–shield, which screens the
whole engine. The metal gasket is used between the PCB and the
shield. The baseband circuitry is located on the A–side of the board,
which is shielded with a metallized frame and ground plane on UI–board.
