Abstract
A transistor oscillator for the microwave band, utilizing CLAPP-circuit configuration, in which a small additional capacitance is connected in series with collector-base capacitance and is disposed between the base and ground. The additional capacitance may be in the form of a trimming capacitor, varactor elements or a line section having a length of less than .lambda./4, and where strip line technology is employed high frequency filter chokes may be employed in the form of line sections, each of a length of .lambda./4 whose ends are short circuited over blocking capacitors.
