Pengadun kuadratur pembahagi frekuensi diri 2 hingga 5 GHz yang menggunakan konfigurasi penggunaan semula semasa dengan saiz kecil dan operasi jalur lebar dicadangkan untuk penerima penukaran langsung dan penerima radio kognitif JIKA rendah. Pengadun yang dicadangkan beroperasi pada dua kali frekuensi LO dengan terus menggunakan pembahagi frekuensi flip-flop jenis statik sebagai litar pensuisan LO untuk penjanaan isyarat kuadratur. Konfigurasi penggunaan semula semasa direalisasikan kerana arus dc pembahagi frekuensi dan penguat pemancar sepunya RF berkongsi laluan aliran arus yang sama. Simulasi dan eksperimen mengesahkan bahawa pengadun yang dicadangkan menawarkan operasi jalur lebar, pengecilan dan penggunaan kuasa yang rendah. IC pengadun yang direka oleh teknologi SiGe-BiCMOS 0.35 µm mencapai keuntungan penukaran sebanyak 20.6 dB, angka hingar 11.9 dB dan EVM untuk isyarat QPSK π/4-anjakan sebanyak 4.4% pada 2.1 GHz dengan penggunaan kuasa 15 mW dan saiz 0.22

Abstract: A 2 to 5 GHz-band self frequency dividing quadrature mixer utilizing current re-use configuration with small size and broad band operation is proposed for a direct conversion receiver and a low-IF receiver of cognitive radio. The proposed mixer operates at twice the LO frequency by directly using a static type flip-flop frequency divider as the LO switching circuit for quadrature signal generation. The current re-use configuration is realized because the dc current of the frequency divider and the RF common-emitter amplifier share the same current flow path. Simulations and experiments verify that the proposed mixer offers broad band operation, miniaturization, and low power consumption. The mixer IC fabricated by 0.35 µm SiGe-BiCMOS technology achieved the conversion gain of 20.6 dB, noise figure of 11.9 dB and EVM for π/4-shift QPSK signal of 4.4% at 2.1 GHz with power consumption of 15 mW and size of 0.22
