990,250. Semi-conductor amplifier circuits. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 23, 1962 [March 10, 1961], No. 7147/62. Heading H3T. [Also in Division H1] An amplifier comprises a high Q tuned circuit including a unijunction transistor (double base diode) of the type described in Specification 990,249, preceded by a junction transistor which may be connected in the common base or common emitter modes. The double base diode circuit simulates an inductor and this is tuned by a capacitor 54. |
