The NG3028G203 is typically found within the HS10 or NG3028 X-Band (25 kW) transceiver housing.
Role: It receives a low-voltage trigger from the TCU (Transceiver Control Unit) and amplifies it into a high-voltage pulse. This pulse is then sent to the magnetron to produce the radar’s microwave output.
Version Note: This board is often interchangeable or closely related to the NG3028G206. The “G203” variant is specific to certain hardware revisions of the 1100 series.
Common Faults: If your radar display shows a “TRM Magnetron Fatal Error” or “TRM No Trigger”, this PCB is a primary suspect alongside the magnetron itself.
