3.36-/15.24-GHz concurrent dual-band oscillator for WiMAX/WLAN applications

This paper reports a concurrent dual-band oscillator using two HEMT transistors and a single dual-band matching network. The device simultaneously oscillates at frequencies 3.36 GHz and 5.24 GHz. Concurrency of the oscillator has advantageous as it provides more functionality, high data rate and system compactness in a single hardware. The measured characteristic of the proposed prototype shows an output power of -9.99 dBm at 3.36 GHz and -15.58 dBm at 5.24 GHz. It exhibits a phase noises with 10 MHz offset as -102.86 dBc/Hz and -93.80 dBc/Hz respectively at designated bands.
