Abstract

Based on the substrate integrated waveguide (SIW) technology, a novel low phase-noise concurrent dual-band oscillator with single active device and a SIW duplexer, which is composed of two mutual-coupling resonators, is developed. This is a cost-effective method to achieve low phase-noise dual-band oscillators. At 2 V and -0.4 V power supply voltage, the concurrent dual-band oscillator generates two carrier frequencies simultaneously, and the output power is -20.34 dBm at 8.29 GHz and -8.23 dBm at 15 GHz. The proposed oscillator features low phase-noise of -107 and -103 dBc/ Hz at 100 kHz offset from 8.29 and 15 GHz, respectively.
