Abstract
1,197,308. Electric component assemblies. SANDERS ASSOCIATES Inc. 23 Oct., 1967 [22 Nov., 1966], No. 48153/67. Heading H1R. [Also in Division H3] A micro-miniature cavity type oscillator or amplifier employs an integrated circuit assembly within the cavity. In an H.F. oscillator embodiment (Fig. 1) a cavity resonator 10 including coaxial inner and outer conductors 12, 14 respectively has an end cap 16 on which is mounted on insulating pad 20 of beryllium or aluminium oxide carrying a thick film type conductive layer 22 of gold, silver or platinum divided into four conductive sections 22a, 22b, 22c, 22d by etching away perpendicular strips. Components comprising a transistor 30 (with cases removed) on R.F. choke coil 36, resistor 38, capacitor 42 and a capacitor 48 are mounted on and are interconnected by the conductive sections as shown diagrammatically in Fig. 2. Supply terminal posts 24, 26 are also provided. The end cap 16 is press fitted into the cavity and a spring member 50 connected to inner conductor 12 contacts section 22a thereby connecting the collector junction of transistor 30 to conductor 12 while an annular flange member 18 engages the outer conductor to connect it to earth potential via post 26. A second end wall forms a short circuit betw een inner and outer conductors 12, 14. An inner conductor 58 of a coaxial output probe 54 in the second end wall forms a coupling loop 60, and the probe may be a plunger device whereby the tuning of the cavity is changed according to the length of probe protruding into it. The cavity may also be tuned by means of a screw 62, adjustment of which into and out of the cavity varies the capacitance thereof. The cavity 10 provides one reactance and the internal stray capacitances 66, 68 of the transistor provide the others to form a parallel tuned circuit. In a further embodiment Figs. 3, 4 (not shown), an amplifier is provided. The construction is similar to the oscillator arrangement, but there are two cavities having a common wall. Alternatively, thin film or hybrid circuitry may be used; also a plurality of transistors may be parallel connected in the oscillator circuit, or series connected in the amplifier embodiment.
