Abstract
A push-push oscillator circuit with a first oscillation branch with a first active device and a first tank adapted to provide a signal having a fundamental frequency f, a second oscillation branch with a second active device and a second tank symmetrical to the first oscillation branch and adapted to provide a signal having the fundamental frequency f. Output branches are coupled to the first oscillation branch and the second oscillation branch to provide signals having the second harmonic frequency 2fof the fundamental signal based on the signals having the fundamental frequency fand/or to provide signals having the fundamental frequency f; The push-push oscillator circuit further comprises at least one terminal branch with a terminal adapted to provide a component of a differential signal having the second harmonic frequency 2for the fundamental frequency f. The at least one terminal branch comprises a RF stub.
