A novel injection-locked oscillator MMIC with combined ultrawide-band active combiner/divider and amplifiers
A subharmonically injection-locked oscillator (ILO) MMIC for local oscillators, synthesizers, and phased-array antennas is proposed. An ultrawide-band four-port active combiner/divider in the oscillator feedback loop provides an FET-oriented circuit topology extremely suitable for single-chip integr...

Summary: | A subharmonically injection-locked oscillator (ILO) MMIC for local oscillators, synthesizers, and phased-array antennas is proposed. An ultrawide-band four-port active combiner/divider in the oscillator feedback loop provides an FET-oriented circuit topology extremely suitable for single-chip integration, and performs subharmonic injection locking at various subharmonic factors, 1/n. Two types of ILO MMIC's were constructed. One of them exhibits a locking range as wide as 1 GHz at n=1, and the other operates at n from 1 to 16, with an output power larger than 5 dBm. The proposed ILO MMIC is promising for applications such as microwave and millimeter-wave synthesizers, large-aperture phased array antennas, frequency-selective FM-receivers, and so on.< > |
