The History of the Magnetron from WW2 Radar to the Kitchen and beyond, by Professor Mike Underhill G3LHZ.
October 23 @ 20:00 - 22:00
Mike will bring a (disassembled) maritime radar and its antenna and show how its magnetron differs only in one main respect from the magnetron in a microwave oven. He will also use it to explain how pulse radar works. But modern radar is now solid state and often uses a phased array architecture. LDMOS semiconductors as now used in UHF solid-state amateur linear-amps are beginning to replace the magnetron in the kitchen. Could the solid-state microwave oven provide cheaper UHF linears in the future?
