Receiver Module from German "Lichtenstein" BC (FuG 212G-1) Airborne Radar, 1942. This worked on a wavelength of about 60cm and the unit consisted of:
1) Anode-triggered transmitter oscillator around triode LD1 with about 1kW pulse-peak output power;
2) Receiver detector around double diode LG1, the transmitter resonant circuit acting as receiver tuned circuit.
The German "Lichtenstein" BC (FuG 212G-1) airborne radar was used in all types of night-fighters of the German Luftwaffe (German Air Force) during the Second World War and had a target range of 0.2-4km.
