Linear analysis of MESFET injection-locked oscillator array

Abstract

Quantitative expressions on the locking performance of a MESFET injection-locked oscillator (ILO) array are presented using nodal-admittance matrix representation. The formulations are derived on a linear approach, hence they are effective in the ILO array design. The locking performance of the ILO array includes the free-running frequency, output power and locking bandwidth. The derived formulations are verified using the measured results from a MESFET ILO and a four-element ring-type coupled ILO array.
