Abstract
A feedback type microwave oscillator using a three-terminal active element employs both series feedback and parallel feedback and capacitance in its output circuit, thereby increasing the small signal negative resistance, and the output power and its resistance to impedance fluctuations of a load attached thereto.
Claims14
A microwave oscillator comprising:
- a three-terminal active element having first, second and third terminals;
- a first inductive element having one end which is grounded at high frequency and having another end which is connected to said first terminal;
- a resonator circuit connected to said second terminal;
- and
- a first capacitive element having one end which is connected to said first terminal and having another end which is connected to said third terminal, wherein
- an output is taken out from said third terminal.
