Abstract: 861,849. Semiconductor circuits; amplitude modulating systems. MOTOROLA Inc. June 17, 1957 [June 18, 1956], No. 19035/57. Classes 40(5) and 40(6) [Also in Groups XXXVI and XL(b)] A device for producing, amplifying, modulating or rectifying high frequency oscillations comprises a cavity resonator containing a thin semiconductor body arranged to be permeated by the internal varying electric field which varies the resistivity of the body to modulate a current applied therethrough. As shown in Fig. 2 thin semiconductor discs 27 and 28 form part of the casing of resonator 20 and are arranged to be capacitatively coupled to oscillations in the cavity. A current from sources 35 and 36 is arranged to flow from the centre of each disc to its periphery and through the casing. The effective resistivity of the body is varied by the field, so that it acts as a negative resistance resulting in the production of oscillations in the cavity. A modulating signal source 41 may be provided to act in series with the sources 35 and 36, and the output is taken from loop 51. Fig. 5 shows a modified arrangement for amplifying a signal applied to cavity 61 by means of loop 86. A second cavity 62 is coupled to cavity 61 through a thin window 63 consisting of the semiconductor body which operates in a similar manner to that of Fig. 2, to produce amplified signals in cavity 62 with output loop 51. Plates 64 and 65 are normal conducting members forming part of the cavity; pulse or amplitude modulation may be effected by means of signal source 76. By critical adjustment of the battery voltage applied to the semiconductor it is possible to effect rectification to detect amplitude modulation. Fig. 7 shows a further arrangement wherein the cavity is provided with a wavetrap 95, 97, 96 and a coaxial line 25, 100 leading to semiconductor disc 27. The line may be tuned by means of piston 102. A dielectric member 92 consisting for example of polystyrene with barium titanate, is placed between disc 27 and the cavity wall. Other similar arrangements are also described. The semi-conductor disc should have a thickness approximately equal to the skin depth in the casing material at the operating frequency. It may consist of a thin film of germanium prepared for example as described in Specification 853,979, in which Ga is deposited on a crystal of sodium chloride which is subsequently dissolved. Reference is made to the effect of a magnetic field, as well as the electric field, upon the resistivity of the semiconductor.
