✦ Synopsis

An analytic method of microwave bipolar oscillator design, allowing one to define explicit expressions for optimum values of feedback elements and load through bipolar transistor Z-parameters, is developed. A negative resistance concept is utilized to design series feedback microwave bipolar oscillator with optimized feedback elements and maximum output power in terms of the transistor impedance parameters. The design of the ( ) wideband common-base bipolar voltage controlled oscillators VCOs is also presented. Numerical and experimental results verify the validity of the design methods described.
