and elements comprising distributed inductance and capacitance

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Generation of oscillations by non-regenerative frequency multiplication or division of a signal from a separate source > using uncontrolled rectifying devices, e.g. rectifying diodes or Schottky diodes > and elements comprising distributed inductance and capacitance

CPC:

Generation of oscillations by non-regenerative frequency multiplication or division of a signal from a separate source (transference of modulation from one carrier to another H03D7/00) > using uncontrolled rectifying devices, e.g. rectifying diodes or Schottky diodes > and elements comprising distributed inductance and capacitance

No child classifications to compare. This is a leaf node in both IPC and CPC.
