Class Information
Number: 331/96
Name: Oscillators > With distributed parameter resonator
Description: Subject matter wherein the frequency determining means or resonator of the oscillator is of the distributed network type, the capacitance, inductance and resistance of which cannot be isolated into separate lumped capacitors, inductors or resistors and wherein the time factor of propagation of wave energy in the network is appreciable. Examples of such a network are an open-circuited or short-circuited wave transmission line a quarter wave length long at the desired resonant frequency. Included are transmission lines wherein the principal wave may be of TEM mode (e.g., parallel wire and coaxial lines) or E or H mode having longitudinal as well as transverse wave components (e.g., hollow conductors, dielectric rods, single wire surface-wave mode wave guides).
