Injection Locking of an IMPATT Diode Oscillator by Using a Low-Frequency Signal Parametric Injection Locking
H. Okamoto, Masahiro Ikeda · 2005
A new injection locking process is proposed and demonstrated experimentally, where a low-frequency injection signal can be used to lock an ultra-high frequency solid-state oscillator. This process has much wider locking bandwidth than the conventional subharmonic injection locking.
