Abstract: A compact solid-state oscillator-transmitter which includes a transistor within a small can defining a tuning cavity. The can is electrically connected in the output circuit to present a capacitance which may be varied by manual adjustment of a tuning screw so that the effective output impedance, including parasitic impedance, has the proper phase angle necessary to permit oscillation at the desired frequency. The can is also utilized to shield radiation of radiofrequency conducting circuit components, to secure the components, and to protect the same against adverse environmental influences. A probe is provided to pick up oscillatory signal energy in the cavity and is utilized as an antenna when transmitting the produced signal.
