WIDEBAND MECHANICALLY AND ELECTRONICALLY TUNED NEGATIVE RESISTANCE OSCILLATOR

摘要

A wideband mechanically and electrically tunable negative resistance oscillator is disclosed wherein a low Q cavity is coupled to a high Q cavity at one end thereof by a narrow gap. A negative resistance R.F. diode is disposed in the low Q cavity in good heat conducting relationship with a massive heat sink. At the other end of the high Q cavity there is the mechanical frequency adjusting structure for tuning the high Q cavity over a wide frequency range. At one side of the high Q cavity, there is a varactor diode for electrically tuning the high Q cavity over a relatively small frequency range. At the other side of the high Q cavity there is a power take out structure.
