Applications of crystal rectifiers at frequencies up to 10,000 megacycles

The Paper first briefly describes the construction and general mechanical details of crystal rectifiers and then goes on to consider their application at microwave frequencies. The design of a crystal frequency changer for a centimetric superheterodyne receiver is discussed in detail and the first section concludes with a consideration of crystal detectors in microwave detector receivers, both with and without amplifiers. The second part of the Paper considers crystal rectifiers for lower frequencies than microwaves; firstly, as second detectors in superheterodyne receivers and then as rectifiers for meters and other general applications.
